Zap is a wonderfully good sport to welcome back the rabble that embarrassed itself during the 1969 Zip-to-Zap.

The mayor notes that this 40th anniversary features a polka band as a concession to the increasing decrepitude of the original Zip-to-Zappers.

That generation does have wrinkles, bifocals and a bit of urinary incontinence; its hair is gray or gone; and its behavior is, ah me, now almost entirely law abiding. But I guarantee it still loves rock 'n' roll. Here are a few of those hard-charging songs that got people out of their chairs in that era:

"Revolution" - The Beatles

"Jumpin' Jack Flash" - The Rolling Stones

"I Fought the Law" - The Clash

"Born to be Wild" - Steppenwolf

"Sympathy for the Devil" - The Rolling Stones

"Bad Moon Rising" - Creedence Clearwater Revival

"Get Up (I Feel Like Being a) Sex Machine" - James Brown

"Marrakesh Express" - Crosby, Stills and Nash

"Whole Lotta Love" - Led Zeppelin

"I Shot the Sheriff" - Bob Marley

"Rock and Roll All Nite" - Kiss

Not exactly Lawrence Welk. And I'm confident it's a generation that can still, as the MC5 sang back then, "Kick Out the Jams."
