The label's most significant signing was 10cc. Eric Stewart, one of the band members, had known King since 1965, when Stewart was with The Mindbenders and King had wanted to manage them. The band had planned to release "Donna" as a B side, but decided it could be a hit: "We only knew of one person who was mad enough to release it," Stewart said, "and that was Jonathan King." King gave the band its name and released two of the group's albums ("10cc" and "Sheet Music") and eight singles. "Donna" (1972) and "Rubber Bullets" (1973), reached number two and one respectively, followed by "The Dean and I" (1973) and "The Wall Street Shuffle" (1974). The band only dented the American market, with "Rubber Bullets" making 73 on the Billboard Hot 100. 10cc left UK Records in 1975 for Mercury Records, after which they achieved success in America, particularly with "I'm Not in Love" (1975).
