Notes: Ben Tucker's original goes to C min. 7 at bar five. Other versions, like Michael Bublé's, substitute F dominant. Alter it according to your taste. (If you're singing it, you should credit the lyrics to Bob Dorough.) I used the "Jazz -Blue Note" setting here - since iRealb doesn't offer Boogaloo.
Edit: May I recommend you give a listen to Bob Dorough's "I'm Hip" - it is priceless!
