"Superstar" is the title song from the 1970 rock opera Jesus Christ Superstar written by Andrew Lloyd Webber and Tim Rice. It was released as a single in 1969, before the album was completed. Sung by Murray Head with the Trinidad Singers, it initially debuted on the U.S. Billboard Hot 100 singles chart for the week ending 31 January 1970, eventually peaking at No. 74 in late February of 1970. Nearly one year later, the single then re-entered the Hot 100 chart for the week ending 2 January 1971, eventually peaking at No. 60 on the chart in early March of 1971. The single then fell off the chart three weeks later, but then almost immediately re-entered the Hot 100 chart a third and final time for the week ending 10 April 1971. It then rapidly climbed the Hot 100 chart during its third chart run, eventually spending two consecutive weeks at its peak position of No. 14 in late May and early June of '71. It performed even better in Canada, where it peaked on the Canadian RPM Top Singles chart at No. 6, its highest known position worldwide.
