The Gift That Keeps On Giving

One of my favorite Who songs is "Pictures Of Lily." It's about a boy who can't sleep until he puts some pin-ups on his wall.

I'd always assumed Lily was just a name they picked at random, but it recently occurred to me maybe it's a specific Lily. Then it hit me--could it possibly be famous turn-of-the-century pin-up Lillie Langtree?

The only clue in the song is when the father tells the son "she's been dead since 1929." I checked and, sure enough, Langtree died in 1929. Gotta be. (I've since discovered I wasn't the first to guess this.)
