In 1969 the tune was used in the Yellow River Piano Concerto. The Concerto was produced by Jiang Qing and adapted from the Yellow River Cantata by Xian Xinghai. When she adapted the Cantata, Jiang added the tune to "The East Is Red" in order to connect the Concerto with the themes of the Cultural Revolution.[12] After China launched its first satellite, in 1970, "The East Is Red" was the first signal the craft sent back to Earth.[2] But its place as the unofficial national anthem was finished that same year, for in commemoration of the 21st anniversary of the founding of the People's Republic, The March of the Volunteers began to be played, albeit only in its instrumental version, once again in all national events.
