An early harmony vocal group most famous during World War II, the Merry Macs formed around Ted, Judd, and Joe McMichael. The brothers, raised and based in Minneapolis, began singing at an early age, with their mother as an occasional melody vocalist. In the mid-'20s, the trio made the leap to radio and toured (as the Personality Boys) with Joe Haymes. By 1930, they had added a female vocalist, Cherry MacKay, and become the Merry Macs. After signing to Victor in 1932, the group made their label debut with "In the Little White Church on the Hill." The quartet recorded only sparingly during the '30s (and replaced Mackay with Helen Carroll), but toured with orchestras including Glenn Miller's. After Carroll was replaced by Mary Lou Cook, the Merry Macs signed to Decca and hit the charts in 1939 with "Ta Hu Wa Nu Wa (Hawaiian War Chant)."
