In 1973, Redbone released the politically oriented "We Were All Wounded at Wounded Knee", recalling the massacre of Lakota Sioux Indians by the 7th Cavalry Regiment in 1890. The song ends with the subtly altered sentence "We were all wounded 'by' Wounded Knee". It charted in several European countries and reached the No. 1 position in The Netherlands but did not chart in the U.S. where it was initially withheld from release due to lyrical controversy and then banned by several radio stations due to its confrontation of a sore subject. DePoe had left this band in 1972. He was replaced by Arturo Perez (1939- ), but later by Bellamy's Filipino-Chicano cousin, Butch Rillera around that point. Following this the band achieved much of their commercial success. Tony Bellamy (guitar, piano and vocals) left the band in 1977, with Rillera leaving shortly after.
