Entered from booking ledger and New York Times concert listing and review. The review only mentions a few of the performers by name, so there may have been additional musicians, and it is unclear whether both Reba Paeff Mirsky and Helga Tustin performed, or if Ms. Tustin replaced Ms. Mirsky for the performance.
