Only once, at a regional-theatre performance of GYPSY. I've had to do/sit through so many bad shows I can take a lot of garbage, but this went over the top. The Mama Rose appeared to be on Lithium and was half-belting, half-mixing the songs, and during "Everything's Comin' Up Roses", Herbie and Louise started talking and laughing to each other in the background--not even pretending to listen to her! (Not that I blame them, but could anything be more inappropriate?) I just couldn't stand to hear her butcher "Rose's Turn" in the same way, so I ran for it.
I ask in all honesty/What would life be?/Without a song and a dance, what are we?/So I say "Thank you for the music/For giving it to me."
