Here is a clip from The Lemon Drop Kid
Bob Hope and Marilyn Maxwell singing
"Silver Bells" is a classic Christmas song, composed by Jay Livingston and Ray Evans.
"Silver Bells" was first performed by Bob Hope and Marilyn Maxwell in the motion picture The Lemon Drop Kid, filmed in July-August 1950 and released in March 1951. The first recorded version was by Bing Crosby and Carol Richards, released by Decca Records in October 1950. After the Crosby and Richards recording became popular, Hope and Maxwell were called back in late 1950 to refilm a more elaborate production of the song. --From Wikipedia
