The evening performance of Trainspotting starts at 9:30, if curtain is actually exact. I would love to see both, but don't want to be that person who is late to curtain. For those that saw either, is it wishful thinking?"
I mean, MAYBE you could make it. I'm guessing Trainspotting starts 5 minutes late like most shows, and Straight White Men was pretty much exactly 90 minutes when I saw it. And the walk over there should be about 5 minutes. So like, you're playing with fire a bit, but it could potentially work. It really depends on where you're sitting at Straight White Men. If you're in the front of the Orchestra in the middle of a row, you're chances are much worse than if you were in the back on an aisle - where you could just bolt as soon as the show ended.
But if you ask me, Trainspotting isn't worth the stress that this would cause.
