The Buchanan Brothers were two brothers, Chester and Lester Buchanan, who recorded country music during the 1940s on the RCA Victor label. Their biggest hit, Atomic Power, reached #6 on Billboard's "Most Played Juke Box Folk Records" chart in July 1946; the song was also featured in the 1982 movie The Atomic Café. Another song, 1947's "(When You See) Those Flying Saucers", was used in the opening scene of the 2009 animated release Monsters vs. Aliens.
Their releases were under two different artist names: "The Buchanan Brothers (Chester and Lester) Singing with Orchestra" and "Buchanan Brothers and the Georgia Catamounts."
They are not to be confused with the pop-rock trio by that name from the late 1960s, which included Terry Cashman, Gene Pistilli, and Tommy West.
