Ah, I knew there would be someone else here that was going!
If you’re going to the second show and want to be up close to the stage, a good hour to hour and a half early. I don’t think for $150 a ticket they’ll make those attending the 1st show go back outside to line up for the second, but you never know. I bet they’ll have us wait at the bar.
I have been to the Troubadour many times, great venue in that I could always show up right before showtime and still be able to be up front, albeit to the far side, at any show I’ve seen.
