Interval Concert: John Wummer, Flute, David Freed, Cello, and Joseph Wolman, Piano All-Bach Program Entered from booking ledger and New York Times advertisement. The ledger lists the event as "Midnight", but the Times ad shows 11:30 PM, and since it reads "Twice Tonite", it is assumed the program from 8:30 PM was repeated. Ticket prices were advertised at $1.50 and $2.00. "Display Ad 122 -- no Title." New York Times (1923-Current file), Sep 28 1956, p. 24. ProQuest.
