Dave Winer, in an act of valuable public service, has posted the lyrics to "Got My Mojo Workin'" here.
This cleared up some decades-old misconceptions for me. For instance, I had interpreted the line "I got some red-hot tips I have to keep on ice" as having something to do with a choice portion of the female anatomy "keeping Hell on ice."
Come to think of it, though, "keeping Hell on ice" is a pretty cool phrase...
