don't complain people...honestly, the only thing more retarded than that is Bono with his shaker...conan always starts at 12:37 EST. Officially. If you don't believe me, watch tonight, 12:37 on the dot.
Secondly, U2 knew the time they were due off...conan even said U2 will play us out, which never means a song is done...in fact, the commercials were dead on last night, which is rare for a music segment.
thirdly, it's called television...if you end a song, and then fade to black during applause, it doesn't resonate as much as leaving mid-song...it gives rockafeller a sense of fun and exitement...
in fact, they rehearsed going out at the start of the bridge, like they did, so please stop complaining. They could have left early for commercials into carson's block after Stuck....And how do I know all this, my friend works on set at Conan.
