When the nuptials were announced for His Royal Highness Prince Harry and Miss Meghan Markle, the song came back to the Corrimal musician’s mind. It had never been released so Mr Devlin, 80, decided to gift it to the couple as a wedding present.

“I just thought that they were a lovely couple, very much in love,” he said.

“I said ‘look, further down the track if you felt like it you could it include it on an album … to raise money for whatever charity that you choose’.”

Mr Devlin didn’t expect any return correspondence but to his surprise he received a letter of thanks from Kensington Palace this week.

“[They] very much appreciated your incredibly kind though, and were so touched that you took the trouble to send a gift,” wrote spokeswomen Claudia Spens.

The letter is to be framed and will sit alongside Mr Devlin’s rock’n’roll memorabilia – like a photo taken of him on tour with The Beatles.
