There was another aggregation founded after the Alegre All Stars, the Cesta All Stars, in which Charlie Palmieri also played: https://www.discogs.com/artist/1101421-The-Cesta-All-Stars. AFAIK there were six Alegre All Stars LPs. Five by the Cesta All Stars. The Alegre tapes are owned by Fania, which is now owned by Concord. Since Craft is part of the Concord Music Group, why not .... Send them a suggestive mail.
Charly did a CD compilation of the Alegre All Stars many years ago, which is nice. Just saw that Fania reissued exactly that compilation!
