I'm putting out an all-points bulletin: I NEED an mp3 of Interboro Rhythm Team's subway-themed 1983 rap single, "Watch the Closing Doors" (lyrics here -- "50th Street - Radio City / Got tickets to Prince and you're looking pretty"). I've searched SoulSeek, WinMX, Kazaa, and the internet, all to no avail. (Update: Found it! Hooray for novelty rap!)
