Daughtry were shit. In 2000 Gotthard opened for some shows and they were awesome as usual.
The U2 shows (in Europe) were no "festival"-like shows. At Wembley there were terrible opening bands like Glas Vegas and Elbow who no one outside the UK knew and the were absolute crap. I'd prefer it the Springsteen way - no support act at all. As Jon copied SPringsteen from time to time he should do that as well here and he should play 30 min longer...
