Female military band in the United States Marine Corps
Women began enlisting in the USMC in July 1943 and musicians attended recruit training prior to being admitted into the band. Four senior musicians from the United States Marine Band at Marine Barracks, Washington, D.C. arrived in November to assist with the training of this up and coming band. Within 2 and a half months, the band grew from 15 to 37 members. By 1944, other ensembles formed within the group, including a Dixieland ensemble and dance band. In addition to its duties at Camp Lejeune, the MCWR Band conducted three tours, two during the war and one during the post-war period as a welcome home celebration. Its first tour was in 1944 and domestic in nature, stopping at USMC bases on the east coast such as a base in Chicago. The tour lasted just over a month and consisted of dozens of concerts, parades, and just 5 radio shows. On 14 November 1944, one of the latter events was fulfilled with its sit in for the weekly Dream Hour by the President's Own Marine Band broadcast. The band was conducted by Charlotte Plummer Owen.
