"Mike Oldfield's Single" is the debut single by musician Mike Oldfield, released in 1974.
The A-side is a variation of one of the themes from Oldfield's 1973 debut album, Tubular Bells, and was made in response to an American single containing an excerpt from Tubular Bells which Oldfield did not authorise.
After its use in the box office success The Exorcist, "Tubular Bells" (as featured on the American single) reached #7 on the U.S. Billboard Hot 100.
