Time estimates for the concert tonight

GREG: OK. So. Doors open at 7. Opening band starts at 8.
BRETT: They're done at 9:30. The main band goes on at 10.
GREG: They play all the crappy songs off their new album for an hour.
BRETT: They play old, crowd-pleasing radio hits until 11:30.
GREG: We get there at midnight, to catch the encore with the heartfelt acoustic number.
BRETT: ...and the showstopping cover of some Kinks' song.
GREG: OK, great... hey, which band are we seeing again?
BRETT: I forget. I think they were big in the 90's. Or 80's.
