Billy Joel won't be massaging the ivories for awhile. The "Piano Man" shattered his wrist during a nasty spill last Saturday night at his Sag Harbor, LI, pad. Joel was inspecting some work his contractors have been doing.

When he went to flip on the light switch near some stairs, he discovered - the hard way - that workmen had moved it. Joel was treated at Southampton Hospital, where he had five pins inserted into his wrist. "His doctor says he'll make a full recovery," says Joel's rep.

Trouper that he is, Joel still plans to appear at Andre Agassi's charity benefit in Vegas this weekend. He'll be singing - but not playing - with Elton John.

It looks as though the "Piano Man" will have to take a break from the ivories for a while.

According to the New York Daily News, Billy Joel has broken his wrist in a fall at his home.

Joel's publicist told the News that the singer/songwriter will make a full recovery. Doctors used five pins to put his wrist back together.

Joel, 54, wrapped up the most recent leg of his and Elton John's "Face 2 Face" Tour in May. No additional tour dates are currently scheduled.

Billy Joel is a gamer. Only one week after shattering his right wrist after falling down the steps in his Sag Harbor home, Joel was onstage Saturday night at Andre Agassi's annual "Grand Slam for Children" benefit concert at the MGM Grand hotel in Las Vegas. And yes, The "Piano Man" played the piano for several songs - though it was only with his left hand.

Joel broke his wrist, which doctors at Southampton Hospital needed five pins to set properly, while inspecting construction work in his home. He reached for where the light switch used to be and found an alarm box instead. In the dark, he fell down a flight of stairs, spokeswoman Claire Mercuri said. "The doctors expect him to make a full recovery," she said.

Billy Joel's daughter Alexa Ray hopes to follow in her father's musical footsteps. The talented pianist and singer has left the Ross School in East Hampton to spend her senior year at the Professional Children's School on West 60th Street. "A lot of folks at Ross are sad to see her go - especially the parents who liked to be able to say, 'My daughter goes to school with Billy Joel's daughter,'" tattles our source. "And they'll also miss rubbing elbows with Billy and Christie Brinkley at school events."

In the odd little show "Movin' Out," a hot, 11-piece band performs 29 Billy Joel tunes while a company of Twyla Tharp ballet dancers twirl, plie and pirouette through a story told only through dance.

I have to be honest: I spent two hours mocking the whole ridiculous affair with disparaging remarks in my notebook, but go figure: When it was over, there I was, standing with everyone else. I was cheering not only for a sensational young "Piano Man" named Michael Cavanaugh (who sounds like Joel, only better) but an ensemble of amazing, sweaty dancers.

Through songs such as "Scenes From An Italian Restaurant," "The Longest Time," "The Stranger," "Captain Jack," "The River of Dreams," "Keeping The Faith" and the emotional peak, "Goodnight Saigon," a pretty spectacular narrative somehow gets told about six '60s Long Island teens whose lives are wrecked by Vietnam.

Joel's hardest-core fans will be mortified by the sight (not the sound) of it, but ballet enthusiasts are loving their foray into "tough-guy" territory.

Pop punk Pink was so upset when her idol Billy Joel turned down the chance to work with her, she made a point of making him regret his decision at this year's (2003) Songwriters Hall of Fame Induction Ceremony.

The singer had hoped to persuade Joel to work with her on her latest album "Try This," but the "My Life" crooner wasn't interested.

Pink says, "I was like, 'No one's ever turned me down before! Who do you think you are?'"
