If one of your favorite bands get back together, go see them AS SOON AS POSSIBLE. Do not think that you can wait for the next leg. I lived overseas when the VU got back together and about a dozen of my friends flew to Paris to see them, and I did not. I woefully underestimated the scope of the Reed/Cale animosity and as a result, I never saw Sterling Morrison play guitar, which remains one of the great regrets of my rock and roll life.
He would have been 70 today.
