Me too, on July 2 1990 in New Brunswick. I won't ever forget it not just because Bowie was awesome but because a woman that climbed on stage to grab Bowie's arse leapt over the barriers and landed on my girlfriend, knocking her out.
I had to lift Em over the barrier so the roadies could take her off to get medical treatment and I spent the rest of the concert trying to find her. Poor Em was a bit stunned by the blow so when they asked her if she wanted to meet Bowie, she said, "no, I need to find my boyfriend."
She was fine, the doctors kept her for observation. Of course, back then we didn't have cellphones so it was tough to reconnect, but eventually the concert staff tracked her down.
She and I dated for a few more months but kinda drifted apart as teenagers do, though we're still keep in touch. That's always a fun memory to relive.
Paul McCartney and Co. put together a concert to cheer us up (https://en.wikipedia.org/wiki/The_Concert_for_New_York_City), and that was the first time I had a chance to listen to Bowie live.
It turned out to be the last time. RIP.
