Almond, 47, was riding as a passenger on a motorcycle when it collided with a car in central London on Sunday afternoon, a spokesman for the City of London Police said.

He was thrown from the bike and suffered severe head injuries, the spokesman said, adding that his condition remained critical Monday morning. It was unclear if he had been wearing a helmet.

The singer was in stable condition at the Royal London Hospital in the east of the capital, the hospital’s governing body said in a statement Monday. The motorcycle’s driver, who hasn’t been identified, was also seriously injured, police said.

Soft Cell earned a No. 1 hit in Britain and major U.S. airplay in 1981 with “Tainted Love,” their electronic synthesizer-laden cover of a classic Gloria Jones soul song.

Almond and fellow band member David Ball broke up in 1984, and Almond began a successful solo career. He scored another major hit with a cover of Gene Pitney’s “Something’s Gotten Hold of My Heart,” which he sang with Pitney.
