"Hump de bump doop bodu bump de hump doop bop hump de bump doop bodu," sings Anthony Kiedis on 'Hump De Bump', the fifth single from the Red Hot Chili Peppers' Stadium Arcadium LP. He pauses for breath. "Bump de hump doop bodu hump de bump doop bop bump de hump doop bodu bump bump". Is this the best that one the world's biggest bands have to offer us?

Still, this single is as funky as finding Prince locked in your basement throwing some shapes to 'Get Up (I Feel Like Being A Sex Machine)'. Its 30-second percussion breakdown, frantic slap-bass and endearingly daft brass squiggles are undeniably impressive, but there's an uncomfortable whiff about it that we can't quite shake off. Hmm. You know what, 'Hump De Bump' is the sound of four middle-aged men indulging in a mutual self-love session. Musically-speaking, of course.
