It could bring in as much as $30,000.

So what did it say?

According to an article in Rolling Stone magazine:

"Eric, I know I can bring out something great, in fact greater in you that had been so far evident in your music," Lennnon wrote in the draft, dated September 29th, 1971. "I hope to bring out the same kind of greatness in all of us, which I know will happen if/when we get together."

George Harrison had thought about quitting the band at one time, and his replacement surely would have been Eric Clapton, given Eric's close relationship with the Beatles.

Interesting to think about what might have been, no?

The letter will be auctioned off in L.A. today.
