That was Keith Richards, of Rolling Stones fame- and it was a (lame) joke on his part.
EC has a long solo career, was the guitarist in Cream, and was one of 3 legendary guitarists in the Yardbirds (along with Jeff Beck and Jimmy Page).
Currently, he's doing whatever he wants- playing on albums with his idols & mentors like B.B. King & J.J. Cale; sponsoring big music festivals (Crossroads), and whatever befits rock royalty.
Essential songs would include: "Layla" "Cocaine" "Sunshine of your love" and "White Room" among many, many others.
