What a coincidence, as an old golf joke ends. (A man and his friend are playing. There is a twosome ahead of them, very slow. He goes up to inspect. He comes back and says to his friend, “You won’t believe this: It’s my wife playing with my mistress.” A while later, the other man goes up to inspect. He returns: “What a coincidence.”)

Anyway, my Impromptus today contains a report, and reflection, on a visit to the roller derby — in Phoenix, but these leagues are all over, apparently. A friend tells me that there has just been a piece on NPR about this subject: complete with reference to the old movie I have remembered in my column, Kansas City Bomber from 1972, starring Raquel Welch.

Oh, Raquel.

There is a new movie about roller derby — this was the impetus for the NPR piece, I gather — directed by Drew Barrymore. Drew is directing? Two seconds ago, she was the tot in E.T.

Anyway — kind of a coincidence, as I said.
