Not only should all the songs in a show be well-rehearsed, but the show itself should be well-rehearsed. And that entails rehearsing the songs in order - including transitions, instruments changes, gear changes, setting adjustments - whatever is necessary to keep the show flowing along at brisk, yet steady pace.
