Saw a Moody Blues documentary where Denny Laine gave Mike Pinder some good natured ribbing about how he once played a wrong note during a British concert. No matter how much I nail a certain tune consistently on guitar,there are times I inexplicably play a wrong note somewhere.has this ever happened to you during stage performance?Also,how often does SAC rehearse and have you ever rehearse much in the studio?I know the Beatles used to warm up by playing early rock gems like "Rip it Up" and "Ready Teddy".......
