I knew nothing about Miley Cyrus before she twerked her way into my consciousness the day after her duet with Robin Thicke on the MTV Video Music Awards.

Frankly, I haven’t been able to tell any male or female performers under age 30 apart for at least ten years now.

All the guys are identical blurs of scruffy facial hair and skinny suits.

The girls are even harder to distinguish, with their character-less faces and clone-ish hair cuts.

The morning after the show, I kept puzzling over the ubiquitous photos of Cyrus in her ugly rubbery two-piece, with her tongue stuck out and her hair just… weird.

I’d seen that get-up before, or something like it.

But where?

Google let me down. I dug through dusty stacks of old books before I found it, in Cool Cats: 25 Years of Rock ‘n’ Roll Style.

The book came out in 1981, so the photo I was looking for is at least that old, obviously. I’d file it under “very late 1970s.”
