From their event page:

Join Fairmount Park Conservancy and Strawberry Mansion CDC for a starry night at The Yard on John Coltrane Street where we’ll be playing the hit movie, Dreamgirls. Bring a blanket, gather your friends and family, and enjoy this free fall movie screening.

Attendees are encouraged to bring the movie to life by wearing their best shining/sparkling outfits or dressing as their favorite superstar/singer as we dream big in Strawberry Mansion!

Located behind the famous John Coltrane House in Strawberry Mansion, The Yard is a new outdoor public space managed by the Strawberry Mansion CDC at the neighborhood edge of East Fairmount Park.

This programming is supported by Reimagining the Civic Commons, a collaboration of The JPB Foundation, the John S. and James L. Knight Foundation, The Kresge Foundation, and local partners.
