Here is the jazzy original in all it's funky glory. Composed by singer Brian Smith and band pianist Terry Fox, the number was only released on The Flip-Side of a French EP on Vogue Records in 1965. The composition is structurally different than other versions that followed. Specifically at the chorus (or is it a bridge?) . Where subsequent versions changed the chorus to a IV-I-IV-V structure, the original is a descending riff from the IV back to the I. Add in the fact that the dominant instrument is a piano, and you get all sorts of crispy, cool uniqueness here.
Until next time, we'll see you On The Flip-Side!
