I was subbing with a roots blues band in the basement blues club of a hotel on a real slow night. They play Muddy Waters, Buddy Guy, James Cotton Chicago blues featuring blues harp. Real down and dirty stuff.
These guys with heavy NYC accents walked in wearing sharkskin suits, silk ties, thick-and-thins and cuban heels. It was like a scene out of the Godfather.
The biggest guy comes over to me just as we're going on break and lays a $100 bill on my piano and says "the boss wants to hear "New York, New York." The harp player, who was the leader, looks at me nervously and says "go ahead if you know it" and the rest of the band leaves the stage.
I ended up playing the rest of the night as a single doing every NY cabaret tune I knew at least twice and "New York, New York" at least six times.
I walked out of there with ten C-notes, a great story and very satisfied (if displaced) customers.
