Best Concert - Rush, Moving Pictures Tour and Snakes and Arrows Tour (its a tie)
Kansas put on a good show too (around 1980)
Ted Nugent was interesting........I also liked seeing Blackfoot back in the day.
Molly Hatchet was a good live southern band (I own one the guitars they used in studio for the Flirtin With Disaster album). Never got to see Lynard Skynard.
But yeah, best concert, Rush, those guys are at the top of the profession as musicians.
