Heard "Peaches En Regalia" as bumper music on the Randi Rhodes show today, and was quite glad. It may in fact have been the first time I'd ever heard that tune -- or indeed, any Zappa -- on the radio.
I never quite understood why PER (or the Hot Rats album in general) tends to get whipped out as the quintessential FZ (it's the only FZ tune I know of to have made it into the Real Book)-- but I'll readily admit that it's a beauty all the same. To me it sounds like the perfect combination of self-effacing bombast and genuine joy.
I'm sure that's what this clothing company was thinking too. (That's right: the first thing I think of when I hear Zappa is fine men's and women's apparel.)
