Have you ever gone to see one of your favorite bands in concert, just to have them blown off the stage....?

I saw a show that included six bands (in 2001), two of which were Blue Oyster Cult and Bad Company. I REALLY wanted to see BOC and really did not care for BC all that much. BOC took the stage and they sounded like they just woke up after a 30 minute nap after a 48 hour party. They were so slow that after just three songs I didn't care if I ever listened to them again. Bad Company took the stage next and it was composed of the original members and I mean they blew EVERYBODY away including the headliner (Styx). That's not just my opinion, I base that observation on the fans response. Paul Rodgers' (BC frontman) audience participation was fantastic. Somewhere in the middle of his set, he started playing a Beatles medley and everybody kinda looked around at each other like "What the ____?" But in no time, we were eating it up, could've swore the Liverpool Limeys were actually on stage! SO, that day I got new found respect for Bad Company and kinda lost my love for Blue Oyster Cult.
