The Merry Macs Biography (Wikipedia)
The Merry Macs were an American close-harmony pop music quartet active from the 1920s till the 1960s and best known for the hits “Mairzy Doats,” “Praise the Lord and Pass the Ammunition” and "Sentimental Journey." The group also sang on recordings with Bing Crosby.
Formed to play proms in Minneapolis, Minnesota, the group originally consisted of the three McMichael brothers: tenors Judd (1906–1989) and Joe (1916–1944), and baritone Ted (1908–2001). They were discovered by organist-bandleader Eddie Dunstedter of station WCCO, who suggested they perform in masks and dubbed them The Mystery Trio.
In 1931–'32 the McMichaels toured with the orchestra of arranger-composer Joe Haymes, who renamed them The Personality Boys. By 1933 they added a female lead singer, Cheri McKay, and changed their name to The Merry Macs. At Haymes' recommendation, Victor Records engaged the group for one single that year, their first recording.
In 1936 they appeared on several national radio programs, and Cheri McKay was replaced by Helen Carroll. (McKay trained her successor in the group's singing style.) Another record session followed with Ray Noble's orchestra. The Merry Macs started appearing with Fred Allen on Town Hall Tonight starting on November 17, 1937. In September 1938, they signed a contract with Allen for the 1938–1939 season, and they remained until the end of the 1940 season.
