Yes Jim Gordon!
.....3rd in line to Hal and Keltner. Hal handed him any of the extra work he could not handle and that got Jim started. You're right though, definitely a Benny Benjamin behind the scenes guy. For many, Derek and the Dominos is a guitar record, but its actually some of the best drumming on any Clapton album, or any album period, thanks to Gordon. That was a great line-up for EC. Loved his Camcos too.
