Entered from calendar in 3/6/1919 program and advertisement and reviews in the New York Sun, New-York Tribune, and New York Times.

Note that while the program calendar also lists a performance for 3/26, no indication can be found that a second concert took place. The sun. [volume] (New York [N.Y.]), 23 March 1919.
