Strouse, 81, was given a lifetime achievement award by the Gershman YMCA there. He took ill at an onstage talkback after the ceremony and was hospitalized in Philadelphia.

"He has a very serious infection but he is doing much better," Strouse spokesperson Carolyn Rossi Copeland told Playbill.com on May 19.

Strouse, who has battled illness in the past, was still in the hospital on Wednesday and is expected to be transported to a New York City hospital where doctors will continue to get his infection under control, Copeland said, adding, "He's in good spirits."

Strouse, who won Best Score Tony Awards for his work on the Broadway musicals Annie and Applause, is expected to be represented on Broadway in the coming year with the musical Minsky's.

His resume of Broadway scores includes Best Musical Tony Award winner Bye Bye Birdie, plus Golden Boy, All American, It's a Bird…It's a Plane…It's Superman!, A Broadway Musical, Charlie and Algernon, Bring Back Birdie, Dance a Little Closer and Rags. Annie and Applause were also Best Musical Tony Award winners.
