Still and all, the optics depress me. And maybe that's 100% my bad -- I enjoyed the Led Zeppelin one-off a couple of years back. They'd have been roughly this age. Happily for them they're still trim dudes with manes of hair intact.
I dunno. Anymore if I want some re-connection with my own increasingly distant youth, I turn to Nat King Cole. I was probably 30 when I picked up the first CD, which is that "optimum" age for a guy -- young enough to glory in strength, experienced enough to make a good first impression, and moving gently with intent toward a horizon where memories should be (he hopes) predominantly pleasant.
