Magic Christian is the name of the band and ex-Flamin' Groovies member Cyril Jordan is the instigator. They've been around a while but recently inducted Blondie drummer Clem Burke into the ranks and released their second album which is attracting positive attention. Here's a clip of them at Maxwell's in Hoboken, NJ, last week covering the Dave Clark Five. That's Wilson rocking out on guitar at stage right.
Addendum: I mistakenly pegged Cyril as Chris Wilson in earlier post, mea cupla.
