IF the warm-up bands don't want to get booed, then the promoters of the concert need to change their title from "Daughtry concert" to "a concert of several bands, featuring Daughtry".
Three opening bands is ridiculous! By the time he hit the stage, everyone around was tired and angry! As wonderful as the concert finally was, the aggravation put a damper on it. I have never seen so many people leave a concert early (but, it was running too late for people who have lives/jobs).
