The former Beatle began by praising the late Margaritaville singer.

Like everyone else in the building has said tonight, this is one great man, McCartney said.

He was generous, he was funny, he’d done just about everything in his life.

McCartney then delved into his kindness with a heartwarming memory: And I say he was so generous.

I was on holiday with him and I forgot to bring my guitar.

So he had his own guitar strung left-handed for me.

And then the next time I saw him, he’d had one custom made left-handed for me.

So I love Jimmy.

The British singer then recalled being asked to sing for Buffett at his home by his wife Jane Slagsvol.

So I thought I’ll sing one of those songs that I sang to him tonight.

The former Beatle then took to the piano.

During the song, McCartney was joined by the Eagles, who were also good friends of Buffett.
