It's weird. It completely works as a musical composition and absolutely wrecks each of its iconic component songs in the process. Sounds like Diamond Dave should be sprawled over the top of a white grand piano in one of the crappier joints off the Vegas strip.
A first-time listener could be completely convinced that this was just a cheesier-than-usual torch song and never dream the greatness it was made from. I may spend the week listening to it!
