tRump walked out halfway through The Wall Concert by P Floyd in 2010
Roger Waters didn't know that this happened in 2010 at The Garden for the show.
"A couple of years back, I had the pleasure of interviewing Roger Waters, a man who has called Trump “pig-ignorant” and a “nincompoop,” and I told him my story of seeing the president of the United States of America completely miss the point of The Wall. Waters just laughed. “That’s interesting in its symbolism,” he told me. “I’m glad you told me that. I had no idea he was there.”
"It’s doubtful that Waters would ever welcome Trump to one of his concerts: Waters’ most recent tour emasculated Trump during “Pigs (Three Different Kinds),” among other indignities, and he told me he’s planning a 2020 tour especially to rail against Trump during election year. But if the president does show up again, let’s hope he hangs around long enough to see the wall come down. He just might learn something."

and thought that was the best ones I had ever scene. It was beyond a rock concert, it was more like a sight and sound experience. I had to remember to breathe. The fucking moron had VIP seats too! 
Proof right there that he was a fucking moron.
Caught it in Tacoma and raves about it. Then Smerconish reviewed the New Orleans show and dumbasses walking out. I pitched the wife on catching it and so we burned some Skymiles to go to Milwaukee.
Between some sweet seats stage right, great audio quality (and volume better than Tacoma) and the timeliness of the songs themes, it was my personal best show. Of course the spousal accompaniment frosted the cake.
At the end of the show Roger did a high five/fist bump with the front row. We were so close that wifey almost went over a rail to reciprocate.
