He has postponed a concert scheduled for March 31 at America West Arena in Phoenix; a make-up date has not been announced.

Joel, 55, entered the clinic after suffering “a recent bout of severe gastrointestinal distress,” spokeswoman Claire Mercuri told the New York Post.

In June 2002, the singer-songwriter checked into a New Canaan, Conn., substance abuse and psychiatric center. He later said he entered the hospital because he had been abusing alcohol.

Joel has been involved in several car accidents in the past three years, though none has been linked to alcohol or drug use.
