Ian Stewart contributed some trademark boogie woogie piano to 'Broken Head Blues', an instrumental jam that would develop into 'Black Limousine', a track from 1981's "Tattoo You" album. The jam also featured Faces guitarist Ronnie Wood, who was present at the sessions for one night, and got a co-credit on the final track. The song symbolized a return to basics, and is said to be a tribute to Muddy Waters and Jimmy Reed, the latter's 'You Don't Have To Go' not being far away.
