Program title: Grand Testimonial Concert tendered to Miss May Hamaker by her teacher, Mr. Ernst Bauer Note that program does not give a specific start time; only states "on Wednesday Eve., May 25, '92 at Carnegie Music Hall". Since there was a performance of the Urania Scientific Theatre in the Main Hall at 8:15 (newspaper listings from May 25 indicate this was not cancelled or postponed), it is assumed that this recital took place in the Chamber Music Hall (or possibly Recital Hall).
