When I ask if Take It Easy is Northern Ireland's longest running commercial radio programme, John Rosborough is quick to correct me, pointing out that Downtown Radio colleague Big T holds the honours having broadcast his country music show since the day the station launched back in 1976.
But he concedes that his own Sunday night show could well be the runner-up and certainly the longest running commercial mainstream music show.
And this weekend will be a very special time for his legion of loyal fans as Take It Easy goes out on the airwaves for the last time.
John (67) admits he's spent the summer putting a vast amount of thought into what will be the final playlist of Take It Easy, ensuring a good spread of fan favourites across the decades that it's been on air.
Throughout that time, the show has evolved with the times, so listeners this Sunday can expect to hear a host of tracks that he has introduced to his audience, everything from Fleetwood Mac to Passenger and The Adventures and The Eurythmics to Lady Antebellum: "I'm really going to go right across the years with artists that have become synonymous with the show."
Throughout lockdown, John continued to broadcast on Sunday nights, tapping into the archive in order to deliver a Covid-free repeat show from the same week a few years back, with the ads and news removed.
"It was a fair amount of work in terms of doing the editing but it was worth doing in terms of keeping the style of the show close to its roots," he says.
As a child, he grew up in Crossnacreevy in the Castlereagh Hills: "It was idyllic, in that it was in the country but also close to the city.
"My father was a lecturer at Belfast College of Technology and when I grew up my mother ceased to be a homemaker and became a social worker and the almoner at Forster Green Hospital. They called her the 'almanac' - that sounds as if she knew everything!" he says.
"The moment that I can point back to when I became definitely interested in radio was on a family holiday at Butlins Mosney. For people of a certain age, they will remember how Radio Butlins used to come on to wake up all the campers and tell them what would be happening that day. I was fascinated with it.
"When I was 11 I got a radio for my birthday and about two weeks later I discovered this new station - Radio Caroline. It was sailing up to anchor off the Isle of Man and we listened very closely. It was the first time music radio was available all day long.
"Caroline beamed out of the north of England, Scotland and into here, and it had a big local feel to it."
His other great passion was electronics - "I loved building things with circuits' - and he went on to study at Belfast Institute, before undertaking Electrical and Electronic Engineering at Queen's University Belfast, completing his degree just as Downtown Radio launched.
"I was part of the team that was involved in installing the equipment and testing it to get the station ready for going on air," he reveals.
A few years into the Troubles, there wasn't much of a music scene in Belfast.
"Probably my favourite band at the time would have been The Doors," he says. "But we were getting into the time of the Troubles and the city just closed. It was a different city altogether."
But it was exciting to be in at the beginnings of a new radio station - John started in December 1975 and the station had pledged to be up and running by St Patrick's Day 1976.
"We just made it one day ahead of that, on March 16," he says. "First there were the engineers who came in to work in the studios, then the journalists started to arrive, then the presenters - people like Hendy, Big T and Candy Devine started in January.
"March 16 was a bit surreal - everyone was in early as we were opening at 6am. But there was a godsend in the news - Harold Wilson resigned and Downtown station was the first in the UK to flash the news. The journalists were watching the newswires so closely and they put it on air in a newsflash, and that was the start of Downtown's reputation for being a good news producer."
Under the first programme controller, Don Anderson, John worked first as a continuity announcer and then as cover for a classical music show before covering for Paul Prenter's Sunday night show.
"Paul left on November 1976 to become the tour manager for Queen and I started doing it," he recalls. "The show was initially called Nice and Easy, but that conjured up a very old-fashioned kind of music. In September 1977 it became Take It Easy and that conjured up more things like The Eagles - it was a closer match for what the show was doing."
Because Downtown was the first Northern Irish station to broadcast in stereo, John featured items such as the Hi Fi Swap Shop and Sound Advice.
He also featured a Student News spot shortly after midnight on Sunday night targeted at students returning to their studies after the weekend.
"There was a story of somebody who said they were walking along the corridor of the Halls of Residence at Queen's one Sunday night and in every room, Downtown was playing," he says.
In his day job, John progressed to production manager and then head of programming, but Take It Easy series one came to an end in 1990 when Cool FM took over the FM frequency and Downtown was moved to medium wave.
By 2000, he was getting itchy feet and was appointed station director of the new Citybeat station, overseeing an impressive team that included a young Stephen Nolan who was hosting a successful interactive current affairs programme.
Among John's most memorable moments were the station winning five Sony gold awards and a silver and also snapping up the accolade of NTL station of the year 2003.
"It was the sort of station that worked well when everybody felt it was a fun place to be - they were very serious about what they were doing, but they didn't have a very serious attitude," he says.
In March 2004, Ofcom announced that it would be offering a licence for a new Belfast radio station and John was approached by no fewer than five different parties keen to get him on board. He joined UTV's bid, successfully proposing a station aimed at over-45s - and U105 launched on November 14, 2005.
"The best compliment I got was when it started and people were saying it sounded like it had been there for quite a while - I took that as a positive," he says.
Take It Easy series two became a feature of U105 and John continued at the station until May 2008, but carried on with the show until just over a year later, before leaving to take some 'me time', travelling around America, Australia and Europe.
But the radio bug soon bit again and in 2009 he was back conducting a research project for the BBC. Then in the summer of 2010 it was announced that Take it Easy would return to Downtown.
In March 2012, John teamed up with four former colleagues to submit an application for an FM service aimed at the 55-plus age group in Belfast - and Belfast 89 launched in 2015.
Now he plans to take a bit of breather, but he remains involved in the Radio Awards and the RTS.
John says his proudest moments include the awards his stations have won, winning the U105 licence and the award they won for the Downtown drama Voices From The Somme, an honour that was particularly poignant as his grandfather Jim Maultsaid had fought at the WW1 battle.
He also reminiscences about the lighter moments, but admits it will be bittersweet to leave the show: "The listeners have been very constant and loyal and I am going to miss having that regular contact with them."
