My guess would be roughly 9pm, that's close to norm for headliners.
In my experiences, headliners usually don't start until 2-4 hours after doors opening. Doors typically open at 7p. I have seen headliners perform at 9pm, and once waited until 12am! The latter was probably an unusual instance. But definitely a few hours after doors open. Nor sure if Mike Watt is a headliner.
It really depends from show to show.
I sure dont...
