On this day in 1961, the famous cellist Pablo Casals took part in a chamber concert at the White House, at the invitation of President John F. Kennedy. The concert was given in honor of Governor Luis Muñoz of Puerto Rico, the adoptive residence of Pablo Casals. Casals played works of Mendelssohn, Schumann and Couperin, with his own composition, "Song of the Birds," as an encore.

While eminent guests raved over the performance, the cellist's laconic comment was simply, "It went well." Casals could afford to be blasé. After all, he had played at the White House before—for President Teddy Roosevelt back in 1904!

Aaron Copland was also invited to the November 13th White House concert in 1961. In a diary entry, he noted: "Pierre Salinger and Senator Mike Mansfield were at our table. President Kennedy was in full view the entire time… Surprised at his reddish-brown hair. No evil in the face, but plenty of ambition there, no doubt. Mrs. K. statuesque… After dinner we were treated to a concert by Pablo Casals. No American music. The next step."

That "next step" came the following spring. In May of 1962, the Kennedys presented Copland's ballet "Billy the Kid" at the White House for the visiting president of the Ivory Coast Republic, with Copland present as a guest of honor.
