In two movies, Kathryn Grayson sang the aria "Mi Chiamano Mimi" from 'Giacomo Puccini (I)''s acclaimed opera, "La Boheme" (lyrics by Luigi Illica and Giuseppe Giacosa). Miss Grayson's black-and-white performance was done for this MGM film, and her Technicolor reprise, on loan to Warner Bros., appeared in the Grace Moore biopic, So This Is Love.
Although uncredited, David Raksin is named by Dr. Engelstaat as composer of "Toy Concertino" before it is performed. Johnny Green encouraged Raksin to extend the piece to make it suitable for concert performance, resulting in a slightly longer version that received its premiere by the New York Philharmonic on December 19, 1954. It was included in the MGM Records 10-inch soundtrack LP.
