I swear this is true: Back when I was kid my dad had one of those ancient tube radios that only got AM... huge, massive thing with big knobs and a gigantic tuning dial.
Anyway, I used to fire it up without his permission (it was in my parents' bedroom) and I swear, the only music that would come out of it was old big band swing stuff. Here I was, 8 or 9 years old, looking for some rock n' roll, and all this thing would play, no matter where the dial was, was swing.
I thought it was haunted.
