The drummer used to have difficulty getting the countoff tempo correct in the heat of a big gig. I would have to wave him off if he was too far adrift.
This time he counted it off double time and foxed me. Trouble ensued as the deps we use had the opportunity to pretend they weren't familiar and show off by playing it double time.
Then the singer comes in, looking like a deer in the headlights but sounding like a member of The Chipmunks, trying to get all the words out instead of walking off.
We finished hardly any slower than we started, shrugged, and carried on.
To his credit the drummer bought a tablet for keeping it all under control from that day forward.
