Happy to say I've had a LOT of them, but the coolest moment was probably July 4th 2003. My band {The Westside All-Stars} opened for Blue Oyster Cult and ELO. {Sans Jeff Lynne unfortunately}
We were onstage while ELO did their sound check running through their litany of hits. Standing a few feet away while Jeff Tandy busted out the piano riff to "Evil Woman" was pretty surreal.
