Musician Phil Coulter said that playing The Town I Loved So Well, the anthem he composed about Londonderry, at the funeral of his long time friend John Hume, was incredibly poignant.
As Mr Hume's remains were carried from St Eugene's Cathedral following Requiem Mass on Wednesday, Mr Coulter's musical version of the song could be heard drifting from inside.
Speaking to the Belfast Telegraph, Mr Coulter said: "The Town I Loved So Well was the song he loved so well and we have done a duet on that on many's an occasion in some weird and wonderful places.
"It was very poignant for me to play it for John today. It became John's anthem and certainly any time we were in company and I was asked to play the piano, I could be sure that within seconds Hume would be at my shoulder saying 'do the Town'."
Mr Coulter acknowledged his friend's singing capabilities, which he said were like every one else in Derry.
He added: "John could sing and like everybody in Derry, he believed God gave him the right to sing. A lot of other things, he didn't give us in Derry but we all believe he made up for that by giving us voices."
Mr Coulter said he was saddened that due to the coronavirus control measures, the numbers able to attend his friend's funeral were restricted.
He said: "It is sad and surely he deserved a State funeral with all the bells and whistles but there is something just more honest about this.
"This is a Derry funeral and sometimes the pomp and ceremony detracts from the point of it and the real point of it is, for Derry people, to say goodbye to John.
"For those of us who are here, it is not only to celebrate John's achievements as a politician which world leaders have been coming forward to speak about, it is also for us to say goodbye to a very special Derry man.
"It is a Derry occasion and we are immensely proud of John and all he has done for this city, let alone what he has done for the country.
"This place was always special to John and John was always special to us and we are remembering John Hume, the Derry man."
Mr Coulter who has shared a long and abiding friendship with Mr Hume said it was his friend he was remembering.
He said: "I am remembering the John Hume of many a night's singsongs over a few pints in Donegal or wherever it might be.
"There are too many sings-songs in low dives and high rises to recall but we had a lot of adventures in various continents which were all good."
