The singer was hospitalized with chest pains.

PALM SPRINGS, Calif. (AP) – Singer Barry Manilow was back home Monday after a brief hospital stay for stress-related chest pains.

Manilow, 57, was taken to Desert Regional Medical Center because he “was in high fibrillation” after returning to his desert home from New York, spokesman Jerry J. Sharell said Monday. Manilow went home after a 24-hour stay.

“After a series of tests and procedures, his heart rate returned to normal and doctors allowed the superstar to return home,” Sharell said. He said the singer was “resting, joking and doing fine.”

Last week in New York, Manilow and co-writer Bruce Sussman had taken part in “two of the most grueling days of arbitration” in a lawsuit over rights to the musical “Harmony,” Sharell said.

“Harmony” was supposed to run in November in Philadelphia but it never opened because it fell short of its capitalization. A 1997 production at California’s La Jolla Playhouse was a success and played its entire two-month run, Sharell said.

The show, which has music by Manilow and book and lyrics by Sussman, is about the Comedian Harmonists, a group of singers popular during the last days of Germany’s Weimar Republic.

“This is the true definition of heartbreak,” Manilow said in a statement released by Sharell. “It literally broke my heart to sit for two days and watch these beautiful people of the creative team testify.”
