Question: Where was the musician from, who released a single  1971 under the name C. Company about a former United States Army officer convicted by court-martial of murdering 22 unarmed South Vietnamese? 

<P0-S0> William Laws Calley Jr. (born June 8, 1943) is a former United States Army officer convicted by court-martial of murdering 22 unarmed South Vietnamese civilians in the My Lai Massacre on March 16, 1968, during the Vietnam War. <P0-S1>  While not technically exonerated, after three and a half years of house arrest, Calley was released after a ruling by federal judge J. Robert Elliott who found that Calley's trial had been prejudiced by pre-trial publicity, denial of subpoenas of certain defense witnesses, refusal of the United States House of Representatives to release testimony taken in executive session of its My Lai investigation, and inadequate notice of the charges. <P0-S2>  His initial conviction faced widespread public opposition both due to the campaign circumstances of civilian embedded Viet Cong, and due to Calley being singled out as the sole convicted officer in relation to the massacre. <SEP> <P1-S0> Terry Nelson Skinner (born August 24, 1947) was an American disc jockey from Russellville, Alabama, United States. <P1-S1>  Together with a group of studio musicians, Nelson released a single in 1971 under the name C. Company featuring Terry Nelson. <P1-S2>  The single, entitled "Battle Hymn of Lt. Calley", was a spoken-word recording with a musical background which discussed William Calley and the incident at My Lai, for which Calley was court-martialed in 1970-71. <P1-S3>  Originally issued on a small local label, Quickit Records, it was reissued nationally on Plantation Records in April 1971. <P1-S4>  The single reached No. 37 on the "Billboard" Hot 100 charts and No. 49 on Hot Country Songs. <SEP> <P2-S0> The Tet Offensive (Vietnamese: "Sự kiện Tết Mậu Thân 1968" , or "Tổng tiến công và nổi dậy Tết Mậu Thân") was one of the largest military campaigns of the Vietnam War, launched on January 30, 1968, by forces of the Viet Cong and North Vietnamese People's Army of Vietnam against the forces of the South Vietnamese Army of the Republic of Vietnam, the United States Armed Forces, and their allies. <P2-S1>  It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. <P2-S2>  The name of the offensive comes from the Tết holiday, the Vietnamese New Year, when the first major attacks took place. <SEP> <P3-S0> The Việt Cộng (] ), also known as the National Liberation Front, was a communist political organization with its own army – the People's Liberation Armed Forces of South Vietnam (PLAF) – in South Vietnam and Cambodia that fought the United States and South Vietnamese governments, eventually emerging on the winning side. <P3-S1>  It had both guerrilla and regular army units, as well as a network of cadres who organized peasants in the territory it controlled. <P3-S2>  Many soldiers were recruited in South Vietnam, but others were attached to the People's Army of Vietnam (PAVN), the regular North Vietnamese army. <P3-S3>  During the war, communists and anti-war activists insisted the Việt Cộng was an insurgency indigenous to the South, while the U.S. and South Vietnamese governments portrayed the group as a tool of Hanoi. <P3-S4>  Although the terminology distinguishes northerners from the southerners, communist forces were under a single command structure set up in 1958.
