My favourite all-time rock guitar album is "Layla" by Derek and the Dominoes. I got a remixed CD of it recently and have been listening obsessively trying to hear which parts are played by Duane Allman and which by Clapton. (It's not that hard, necessarily, Allman plays mostly upper-register slide).

OK, two things:

1. I heard on a radio phone-in show recently that a secret, uncredited player on some of Layla was the British guitarist Jeff Beck.
   
2. An article on the Clapton-Allman collaboration specifies that they first met after the Layla sessions had started. (A funny story in itself: Clapton had been blown away by Allman's playing on a Wilson Pickett recording, and went to see the Brothers playing in Florida near the "Layla" studio. Duane Allman was in the middle of a solo and looked down to see Eric Freakin Clapton right in front of the stage, staring at him. Duane completely froze up and stopped dead, possibly for the only time in his career.) Specifically the article says Allman did not play on the first three cuts: "I Looked Away", "Bell-Bottom Blues", and "Keep On Growin".
   

I couldn't find any online source that said anything about Beck playing with the Dominoes, so I'm wondering,
WHO PLAYED THE SECOND GUITAR on these tracks? Anyone know if it was Beck?

I haven't listened to a lot of Jeff Beck, but the high guitar parts on those three tracks seem to fit with his style, very physical, dynamic playing, all over the Stratocaster, not a lot of effects.

Any rock guitar historians out there?
