Greg Lake turned 66 on Sunday, born on November 10, 1947 in Dorset, England.

He's working on his book chronicling the extraordinary life of a prog-rock pioneer as frontman of King Crimson and Emerson, Lake and Palmer, and will call it...what else? "Lucky Man".

According to somethingelsereviews.com, Greg says:

“I’ve been writing it for some years now. I keep meaning to bring it out, but every time I get close to it, somebody comes up and says: ‘Greg, do you remember the story about this and that?

And I think: ‘Oh, God, I’d forgotten that.’ And I go and I put it in, you know? I keep going back to it, and adding things. I suppose it’s this fear of just not wanting to leave something out which was important.”

As for a reunion of Emerson, Lake and Palmer?

Drummer Carl Palmer says in an article at ultimateclassicrock.com, that the 2010 reunion performance killed any chances of the band ever getting back together again.

He said, "It wasn’t to the standard that I liked and I didn’t think it sounded that good.”

Greg said in a Rolling Stone interview last spring that it takes a lot of energy and determination to meet the standard of performance that fans expect from a band like ELP.

"The expectation is very high. People are coming to see the legendary ELP. What do they expect?

I'll tell you. They expect to see the band they heard on record or saw on tour in 1974. And now we're 40 years older, and you've got to do it the same. That takes some doing. "

Greg said in that interview that after the autobiography comes out, he's planning to record another album.
