I Love You Truly, musically, was originally a parlour song written in 1901 by the American singer-songwriter Carrie Jacobs-Bond. Five years later she published sheet music for the composition and it sold over a million copies, one of the earliest songs composed by a woman to achieve that distinction. Since then it has been sung at weddings, recorded by Bing Crosby and numerous other artists over the years, and heard on television and in films. James Stewart and Donna Reed are serenaded with a vocal duo rendition of I Love You Truly on their wedding night in the classic Frank Capra fantasy film It's a Wonderful Life. In the Encore Films production the newly-weds dance to an orchestral waltz version of I Love You Truly, while a funky, party-atmosphere vocal arrangement is heard during the end credits.
