The song is "Limehouse Blues" and the references to other songs within the four minutes are many.
Now that's entertainment and I sincerely hope to land a film print of a Borrah Minevitch And His Harmonica Rascals Soundie someday!
Too bad the concept of conductors didn't make it into the rock era (although one could make the argument that such bandleaders as Pete Townshend and David Bowie were, indeed, conductors). The idea of someone like Borrah Minevitch having a bit of fun conducting onstage with, for example, Ray Davies, Jeff Beck, Ron Wood, or even better, Syd Barrett, would have been . . . interesting, to say the least.
