Ha! I will have you know that I LOVE Jethro Tull, and just the other day was practicing "Too Old To Rock and Roll, Too Young to Die" for future karakoe opportunities. I am especially fond of the faux-Robert-Burns era.
Someday I will refine and publish my explanation of how you can tell a lot about a 50-ish white USAian man by what proggish rock group he will admit to having loved. Rush people, Tull people, Yes people, King Crimson people ...
