Top o' the Morning / Emperor Waltz: Bing Crosby had recorded the songs from his film "Top o' the Morning" in May and June 1949 and these were released on two separate 78 records to tie in with the film’s premiere on August 31, 1949.

As the four songs from "Top o' the Morning" only filled one side of the LP, Decca added the four songs from the successful "Bing Crosby – The Emperor Waltz" 78 rpm album to complete the record.
