John Scott Trotter, who arranged orchestrations for Pennies from Heaven, a 1936 American musical comedy film, is professionally associated with Crosby and was asked by Johnny Burke to do orchestrations for a film.
After leaving Kemp's band, Trotter did some work in Hollywood where he handled the orchestrations for Columbia Pictures Pennies from Heaven which was his first work with Bing Crosby. Pennies From Heaven is a 1936 American musical comedy film directed by Norman Z. McLeod and starring Bing Crosby, Madge Evans, and Edith Fellows. This would start a 17-year professional association with Crosby, although Trotter and Crosby had first met in 1929 in New York City at the Manger Hotel while Crosby was working with Paul Whiteman's orchestra. He had been asked by Johnny Burke if he wanted to do the orchestrations for the film.
