I got asked to fill in on bass for a local cover band about 10 years ago for a couple months, while the band found another permanent member. I agreed begrudgingly (Bass? Yuck) only because I was sniffing around with the lead singers chick, who was my coworker. (Another story) These dudes insisted that they play every song in the original key. I kid you not, we changed tunings 15+ times a night. I told them we should just tune to Eb (and go to dropped C# from there for dropped D songs) or conservatively (drumroll) group the songs in the set to the same tuning, because the drunk chicks on the dance floor or the dudes following them around trying to get laid, did not care if the song was a half step down. lol That went entirely over their heads, and away we went playing the tuner pedal for 20 minutes a night. Good times.
