Starts off with about 30 seconds of unaccompanied vocal, sounding quite like Dennis Brown to my untutored ears
"Oooh well well, yeah yeah, yeaaaaaaahhhhh, yeah, weeeeellllllll, too-oo, too-oo, come on come on, come on come on..."
then the rhythm kicks in - a pretty brisk affair with some prominent hi hat and rhythm guitar, then a fairly funky bass line melody and some more of the scat-like vocals reappear about half way through...
Any ideas?
