"My brother's back at home with his Beatles and his Stones; we never got it off on that revolution stuff." So lamented Mott the Hoople in their 1972 "All The Young Dudes," a David Bowie-penned anthem about aimless glam-rockers and their disdain for the values of the past. Oh, those boogaloo boys in their eyeliner, glitter and platform shoes! I've enjoyed glam-rock as much as many other genres, from punk to bluegrass. But no matter how many musical roads I've traveled, I always end up "back at home, with my Beatles and my Stones." This summer, my two favorite bands celebrated 50th anniversaries.
