R’ Shloimele Z”L

In one of the postings (I think it was about music and lipa), someone mentioned that Reb Shlomo Carlebach z’l was considered “a bad boy”. As I am a fervent and avid supporter of Shlomo’s derech and think of him as a Tsaddik, can you, out there, tell me what you think about his music, his Nussach hatefillah and, lastly, his derech in ahavas yisroel. Please be circumspect in your words!
