Just watched a rockumentary on PBS, about a group in New England that covers everything from The Clash to James Brown to Sonic Youth -- "Schizophrenia" to the Zombies "She's Not There."
The interesting part is that the average age of the group is eighty years old. Ranges from 73 on the low end to 92.
Next time you are feeling tired and old, rent this and watch it. It's uplifting, touching, sad, and altogether one of the better shows I've seen lately.
