The chorus, one of the oldest LGBTQ choral organizations in the U.S., was set to perform alongside the National Symphony Orchestra in May.

An event at the John F. Kennedy Center for the Performing Arts featuring the Gay Men’s Chorus of Washington, D.C., and the National Symphony Orchestra has been canceled, the choral group said. The incredible performance was one of the many memorable moments from SNL50: The Homecoming Concert.

The Kennedy Center canceled a concert planned for May 21 that was to feature the Gay Men’s Chorus of Washington, DC, performing alongside the National Symphony Orchestra. The two groups were planning to collaborate on a piece called “A Peacock Among Pigeons,” with GMCW serving as the orchestra’s guest chorus. No explanation was given.
