In the excellent article on Lyman Spitzer *38, Margaret Ruttenberg ’76 mentions Dr. and Mrs. Spitzer dancing to the strains of Richard Strauss.

The piece in question is not specified, but I will go out on a limb here and voice my suspicion that the composer was one of the Johann-Joseph Strauss family of Vienna, rather than Richard Strauss of Bavaria, whose output was primarily opera and lieder.
