Watching all the excitement about Glee's Rocky Horror Picture Show episode, I had one thought: Who knew that the cult classic had such long legs?

I know all too well the power of the campy movie, which has developed a huge following over the years and even has generated many spin-off books. When I lived in Boston back in the day, I can recall dressing up for the show -- with all my clothes on backwards and a lampshade for a hat. I carried the requisite water pistol, toast and other props to the theater, and had a blast in the crowd-particpation event. (That was also the era when an Allston movie house kept Harold and Maude on the marquee for years.)

The sanitized Glee version can't hope to capture that quirky atmosphere. Mom and Dad would frown on kids squirting water around the living room, and hurling toast at the big-screen TV.

But it is nice to see that the young-uns appreciate the classics, ain''t it?
