Very disorganized feeling show, with other performers doing annoying bits or interrupting the main performance - sometimes in periods that were just excruciating to sit through. Gallagher himself was the only one who actually seemed like he was there to do a job and give a performance he'd been paid to do - the others seemed like they didn't rehearse and just wandered in drunk or high. As for Gallagher's stuff, some of it was genuinely funny and enjoyable, some was crude and offensive in a way that's not humorous but just borderline bigoted. I'm not saying that's who he is, but it seems to be the audience/style he plays to.
Tip for others who may go: if you don't want to leave covered in all manner of food goop, buy seats far away from the stage.
