This morning when I woke for the third time (uh, kinda disturbed sleep last night, yeah), I woke with "Snow Magic" playing in my brain (as sung by Anna of Caer Edgemere). An hour and a half later, I had "Gorilla, You're a Desperado" looping in my head ... alternating between Warren Zevon's voice (the way I've actually heard it) and Tom Waits' voice (which just seems like it ought to happen) on successive repetitions.
