"Very Good -" for me.
One of their better b-sides, IMO. In fact most of the Abacab b-sides rank high in the favorites list for me. This one IMO would've been a good album contender. Great vocals, drums etc. The melodic interlude and key changes keep it from becoming monotonous.
It actually has a very Duke sound to me...as if it were something they wrote during the Duke sessions, but didn't record until Abacab....
