I was assuming present all-stars. Shlomo Carlebach and Jo Amar are not available to perform at present.
Reb Chaim Banet seems to be retired except as a composer and he was never a singer – he led choirs but never sang with them. I do not think he covered much new ground with his last album. The Rabbi’s Sons do not sing anymore etc, etc, etc.
Lifetime All-Stars (who are here in this world)
MBD
Avraham Fried
Regesh
Banet choirs
Ben-Zion Shenker

Dovid Werdyger (He is with us and still well at 90 ka”h, but I do not believe he is able to sing anymore).
