In 1944, The Williams Brothers sang backup vocals on Bing Crosby's hit pop standard "Singing on a Star," which topped the U.S. charts that year and the Australian charts the following year. They appeared in the major studio musical films "Janie" (1944), "Kansas City Kitty" (1944), "Something in the Wind" (1947), and "Ladies' Man" (1947).

The brothers signed with MGM to appear in the 1945 movies "Anchors Aweigh" and "Ziegfield Follies" but the studio dropped the quartet after their oldest brother Bob was drafted into military service. However, singer and MGM's head of vocal talent hired The Williams Brothers to sing on the soundtracks for movies including 1946's "Harvey Girls" and 1947's "Good News."

After Thompson left MGM, she and the quartet formed the nightclub act Kay Thompson and The Williams Brothers. From 1947 to 1951, they successfully toured across the United States and internationally. They also appeared on popular radio and television shows.

When the act broke up, Don launched his solo career and performed on "The Tonight Show," "The Eddie Fisher Show" and "The Nat King Cole Show." He also sang in commercials and appeared on a 1956 episode of the TV series "Playhouse 90."
