Dave Grohl, Joan Jett, Ponch ... the unexpected celebrity sightings are all over social media this weekend at Harley-Davidson's 110th anniversary bash is in full swing in Milwaukee. But there are some folks that are likely to steer clear.

1. Jimmy from "Quadrophenia"

As dedicated as the archetypal mod was to purple hearts, northern soul and rumbles in Brighton, Jimmy loved his Lambretta scooter best of all. I wouldn't expect him to be caught dead with a city full of rockers – real or self-styled. Anyway, he was last seen riding out by the cliffs of Dover in 1979, so who knows where he is.

2. Conan O'Brien

Speaking of rumbles, surely, Leno is expected in town. Unless Conan wants to duke it out, it's best he gives a wide berth.

3. Osamu Suzuki

If there's one place Suzuki CEO Osamu Suzuki might not feel especially welcome, it's in hog heaven.

4. Animal

Sure, he's the Muppet-most-likely-to-ride, but still, come on, he's a puppet, dudes.

5. Elsie

"Please don't make a pair of buttless chaps out of me."

6. Elton John

I'd venture to guess there's still a sour taste that lingers.
