I played pit orchestra for Cabaret a couple of years ago, and I hadn't realized that the similarity between the tunes was why I was playing the same wrong notes over and over that sounded so right. (does that sentence make any sense?) They're not exactly the same, though, and Tomorrow Belongs to Me does some neat fuging-type harmonies in the second or third verse. I think it was in the score, although I could be mistaken.
