Best:
Kingsman - 1964, Panama City Fla ( thanks big brother...)
Stones - 1966, HIC in Hawaii ( first 'concert' date )
Greatful Dead - 1974, UW Seattle ( Cartman would have had a seizure. "Hippies in the wall..." )
Live Aid 85, Wembley Stadium, U.K. ( too many pints )
Zappa - 1988, Brighton Arena, U.K. ( the man...)
Jimmy Buffett 2010 Nashville ( Night of "The Flood" )
Worst:
Like something else in life, " there's no such thing as bad concert; some's just better than others!"
