Due to the man's name on the writing credits of the flip side ("Don't Hold On To Someone (Who Don't Love You"), many people assume this is Solomon Burke. Burke himself denied it, and to my ears it's not him either.
The mystery of who this is has never, and probably never will, be revealed.
It's not a major work by any means, but a very fun track driven along by some coochi-coochi-COOL bass playing and some mighty fine singing from "Lukas".
