As previously announced, the 7 PM concert will be hosted by Julie Halston, who joined the cast of Roundabout’s Anything Goes earlier this month.

Directed by Carl Andress, the evening will also feature Tony nominee Andrew Rannells (The Book of Mormon), Mary Testa (Queen of the Mist) and Darlene Love (Hollywood Bowl's Hairspray), who will belt out some of Broadway's most memorable songs. Seth Rudetsky will conduct his seminar on the art of Broadway belting. Jesse Kissel is musical director.

Halston is a spokeswoman and activist for Pulmonary Fibrosis ever since her husband (broadcaster Ralph Howard) was diagnosed with the disease in 2008.

All funds will go toward The Michael Kuchwara Fund for Idiopathic Pulmonary Fibrosis Research, Education and Advocacy in honor of the late and beloved Associated Press theatre critic and reporter.

Doors will open at 5 PM with curtain time promptly at 7 PM.
