Short version.
Several musicians meet up for a natter and Greg Lake says he's going to write a Xmas song, it will be his pension, played every year etc but he's stuck on the lyrics....
They said there'll be snow at Christmas
They said there'll be peace on earth
And that's it.
Other musicians are taking the piss out of him but someone I knew comes up with the next two lines......
But instead it just kept on raining
A veil of tears for the virgin birth
Fast forward a few months and one of the musicians phones friend with the news that's it's out. Friend was unaware.
"But you should get royalties for it, as you wrote some of the lyrics. Friend couldn't be bothered. If I told you his name you'd think I'm making it up, but it's there on a Bowie album. Lovely, unassuming bloke he is as well. He didn't tell me the story, someone else did.
