Cannibal in the Headhunters are one of many forgotten (undeservedly so) garage soul bands from the early to mid 60's. They had a minor hit with a cover of Land of 10,000 Dances, but they have a lot of great material.
This is a great swinging little R+B song. My favorite part is the falsetto "Devillllll, In Disguise" chorus. The band reminds me a lot of some of Ray Charles stuff like Hit the Road Jack.
