Mmm...fun. Like winetarelli, I could make a list of just Clapton stuff, but I will try to avoid.
"Don't think Twice, It's Alright" from Dylan's 30th Anniversary Concert
Pretty much every solo on The Dominos L&OALS (just look at my username)
"Blue Sky" in a pre-release concert from SUNY Stonybrook in 1971
Wilson Pickett (Duane Allman):
I've been an avid collector of Clapton live recordings (call them bootlegs if you will)for about 25 years, and there are many many songs I can listen to over and over and over due to that singular guitar solo. Too many to list here, but he really is at his best on a stage.
