With due respect to the Rosh Yeshiva, it's a cute story, but just plain false, and actually quite insulting. If you don't want to walk out when carlebach sings, that's a legitimate position, but to mock those who had a different position says more about how comfortable you are with your position than them.
You don't have to take my word for it, others here can vouch for my grandfather’s musical knowledge and ability. But more, he knew carlebach, was friends with him. It was extremely painful for him to watch him use his talents in the ways he did.
People didn't walk out because of Carlebach's sexual abuse, that wasn't known or discussed in those days. They protested his flagrant disregard for halacha in the name of bringing people closer to yiddishkeit.
If someone sang a Carlebach song in front of my grandfather, they got a stare down for the ages. Not because he was "tone deaf" - he gave you a similar look if you got a note wrong in Der Pastach - but because of the painful memories it elicited.
Having said that, I don't know that he would have walked out of a wedding, he probably would have stayed and danced with his old friend, even as it pained him to overhear Esa Einai the next day.
That's more connected to what's at play here. When you see, or when your kid sees a Chaim Walder book, what is going to come to mind? I'll never be able to read kids speak without wondering if he based this story on a child he abused emotionally or physically. An abuse survivor who sees people's speak on your shelf will immidiately be triggered and retraumatized.
Does that happen when carlebach music plays? For some, yes, for 99.9% of people no.
I eat most weeks by hagaon eily smith, his wife is citron.. her parents come often and of course bubby carlebach.
Shlomo is the other side, this is his twin eli chaim.
But I certainly learned a lot about the carlebach family of ranbanim.
Shlomo had so much for him and against him. His story is not of any specific steam of Judaism, Lakewood may have judged him for going to chabad but he was very much from Torah im derech eretz world.. his family were the highly respected ranbanim of Hamburg etc..
Shlomo was the story of greater the yetzer tov, greater the yetzer hara.
When I sing ana hashem, I can't pretend to know what Shlomo was thinking when he sang out. Hashem yodea machshavos Adam
Listen, David hamelech wasn't perfect either .. ironically he gave away batsheva!
