"Sentimental Journey" is a popular song, published in 1944. The music was written by Les Brown and Ben Homer, and the lyrics were written by Bud Green. Les Brown and His Band of Renown had been performing the song, but were unable to record it because of the 1942–44 musicians' strike. When the strike ended, the band, with Doris Day as vocalist, had a hit record with the song, Day's first #1 hit, in 1945. The song's release coincided with the end of WWII in Europe and became the unofficial homecoming theme for many veterans. The record first reached the Billboard charts on March 29, 1945 and lasted 23 weeks on the chart, peaking at #1.
