Ok folks,
Seems to me and to some other folks that it was INCORRECTLY credited to Clapton. Like I mentioned, on two separate web sites the discography shows NO mention of Classical Gas. I guess until someone can give us the details on whether it was a single, an EP or an LP (the latter two usually being in CD or Cassette format, and the age of the song would not preclude it from being on a cassette), and the related info to that recording, AND since it is an instrumental, so there would be no vocals to point out it was Clapton, it is still not proven.
I'm sorry folks, I'm a believer in proof makes the conviction.His own web site doesn't show all of his stuff going all the way back, but the one I listed does. Call me an old geezer, but I'd need to see proof, not just " oh yeh! A buddy of mine has a recording of it" or, " It's a really cool version. No accompanyment. Just Clapton on a nylon. I like it better than the original. He adds a couple extra licks, too."
When and where did you hear it? Some details would be cool.
And Understand something, I'm not trying to argue for the sake of arguing. If it is a cool version, don't you think it would be good to share the info so more folks can hear it?

I know if I hear something that is difficult to find, or something new that I really think would be appreciated by others, I direct them to the source of it.
C'mon! Share the love!! Share the Music!!
