This is essentially the same story behind Dire Straight's "Sultans of Swing". A band playing for next to no one, but for the fun of it.

  And Harry doesn't mind if he doesn't make the scene
  He's got a daytime job, he's doing alright
  He can play the honky-tonk like anything
  Savin' it up for Friday night
  With the Sultans
  We're the Sultans of Swing
