In the years just before and during World War II, the Andrews Sisters were at the height of their popularity, and the group still tends to be associated in the public's mind with the war years.
They had numerous hit records during these years, both on their own and in collaboration with Bing Crosby.
Some of these hits had service or military related themes, including "Boogie Woogie Bugle Boy", "Three Little Sisters", "Don't Sit Under the Apple Tree (With Anyone Else but Me)", "A Hot Time In the Town of Berlin" and "Rum and Coca Cola".
The sisters performed their hits in service comedy films like Buck Privates and Private Buckaroo.

During the war, they entertained the Allied forces extensively in Africa, and Italy, as well as in the U.S., visiting Army, Navy, Marine, and Coast Guard bases, war zones, hospitals, and munitions factories.
They encouraged U.S. citizens to purchase war bonds with their rendition of Irving Berlin's song "Any Bonds Today?".
They also helped actress Bette Davis and actor John Garfield found California's famous Hollywood Canteen, a welcome retreat for servicemen where the trio often performed, volunteering their personal time to sing and dance for the soldiers, sailors, and Marines (they did the same at New York City's Stage Door Canteen during the war).

While touring, they often treated three random servicemen to dinner when they were dining out.
They recorded a series of Victory Discs (V-Discs) for distribution to Allied fighting forces only, again volunteering their time for studio sessions for the Music Branch, Special Service Division, of the Army Service Forces, and they were dubbed the "Sweethearts of the Armed Forces Radio Service" for their many appearances on shows such as "Command Performance", "Mail Call", and "G.I. Journal."

The sisters' 1945 hit "Rum and Coca Cola" became one of their most popular and best-known recordings, but also inspired some controversy.
Some radio stations were reluctant to play the record because it mentioned a commercial product by name, and because the lyrics were subtly suggestive of local women prostituting themselves to U.S. servicemen serving at the then naval base on Trinidad.
The song was based on a Trinidadian calypso, and a dispute over its provenance led to a well-publicized court case.
 The sisters later told biographers that they were asked to record the tune on short notice and were unaware either of the copyright issue or of the implications of the lyrics.
