"Saturday Night (Is the Loneliest Night in the Week)", also known as "Saturday Night (Is the Loneliest Night of the Week)", is a popular song published in 1944 with music by Jule Styne and lyrics by Sammy Cahn.[1]
Although it has been interpreted as referring to the separation of romantic partners during wartime,[2][3] Cahn said that song actually refers to show business people who are not working on Saturday night.[1][4]
Charted versions in 1945 were by Frank Sinatra[5] (recorded November 14, 1944, released by Columbia Records as catalog number 36762),[6] (No. 2 in the charts), Sammy Kaye and His Orchestra (vocal by Nancy Norman) (No. 6), Frankie Carle and His Orchestra (vocal by Phyllis Lynne) (No. 8), Woody Herman and His Orchestra (vocal by Frances Wayne) (No. 15) and by The King Sisters (No. 15).[7]
I can go out Sunday, Monday, Tuesday, Wednesday, Thursday, and Friday, but if you're in show business, Saturday night is the loneliest night in the week.
For the first few months of the year [1945], songs of loneliness still abounded until servicemen returned to the states.
Cahn explained that Saturday night is for 'civilians,' but people in the business who aren't working stay home.
