Madness have kick-started a fond farewell to BBC Television Centre with an hour-long, rain-battered concert celebrating the building's 53-year history.
The band's performance outside the west London Grade II-listed building, nine days before TV Centre closes, was the last live event there, the BBC has announced.
Hundreds braved the pouring rain to watch the band belt out their hits including Baggy Trousers, Our House and One Step Beyond.
Front man Suggs told the crowd and hundreds of staff watching from office windows and balconies: "Goodbye Television Centre. I'm going to miss you."
The live concert was broadcast on BBC4 followed by Goodbye Television Centre which was filmed on Monday.
Madness told the BBC: "We've played at some exciting places in London lately but the closing of BBC TV Centre, well, that is close to our hearts, as a band we grew up there, those walls have plenty of Madness tales to tell, a sad day, the end of an era, oh, but what a celebration. We're honoured to be the band the Beeb have chosen for this fond farewell."
The band also played new material as well as a string of classics.
The 1960s centre, once home of Top Of The Pops and Blue Peter, was sold for £200 million and will be made into a shops and offices complex that will include hotels, flats and a cinema.
