Bing Crosby would record the song "Where The Blue Of The Night Meets The Gold Of The Day" for the first time in 1931, and as we all know for the next 46 years it would be his theme song. The song was originally "When the Gold of the Day Meets the Blue of the Night", but the title was changed before recording. Because Crosby contributed to the lyrics of the song, writers Roy Turk and Fred E. Ahlert included him in the songwriting credit. Although the song was popular and successful, Crosby did not take special pride in having written it, saying much later, "I really think I'd trade anything I've ever done if I could have written just one hit song."
Here is a clip from Bing's 1933 short of the same name:
