Paul Anka gave all of the song-writing toyalties for It Doesn't Matter Anymore to Buddy Holly's widow.
That I did know. The two of them went on tour together in Europe & England just before BH died. I wish I'd been a few years older - I may have been able to see them live.
A manager I had at work in Hull saw them. He said he couldn't believe the sound just 3 people made. A few years later that made me some money. We were talking at work some years later and I mentioned this. Someone jumped in, he was a bit like some on here who tell everyone they are wrong without checking first,, and immediately said that was bollocks because there were 4 of them. I went down the library (it was in pre internet days)and found a book with pictures of the tour in it. A while later I steered the conversation round to it again and when he repeated it bet him £20. Next break produced the book. Easy money. There were 4 Crickets originally but one left after a year. Decided to listen to some Buddy on YouTube after reading your post and came across this which .I hadn't seen before.
