(It was - and is - Bach's "Air on a G String," a title which I initially thought was hilarious. Once a lowbrow...)
I fell asleep once listening to Pink Floyd-The Wall and had it on repeat. Woke up with Comfortably Numb stuck in my head for a couple days.
I know that YS piece well, as a Beatles fan m'self, when that part comes on I always exclaim: "Ahhhhh BACH!", in keeping with Hawkeye's advice to Radar when Radar wanted to get friendly with the chick Nurse (in M.A.S.H.)
