Donald Fagen, Walter Becker, and Denny Diaz: You Gotta Walk It Like You Talk It (Or You'll Lose That Beat) (Original Soundtrack) (1971)

I suppose you could look at this record as a pre-Steely Dan record, coming, as it did, about a year prior to the first Steely Dan record. Sadly, it's not as good as Steely Dan, though there are hints. People have to start somewhere.

You Gotta Walk It Like You Talk It (Or You'll Lose That Beat) is a comedy-drama, what we would now call a dramedy.  I have never seen this film, described as a low budget outing. in any case, the record is probably only of interest to Dan fans. like me. Others might not get it.
