Multiple award-winning husband and wife singer-songwriters Amy Grant and Vince Gill will launch a nationwide initiative for Challenge America on June 8. The couple will headline and host the one-night musical event at The John F. Kennedy Center for the Performing Arts in Washington, DC.

The charity’s initiative will work to develop recreational and occupational programs for wounded service men and women, as well their families. In the past nine years, Grant and Gill have raised more than $3.5 million through a variety of events for the regional Challenge Aspen, which has since grown nationally into Challenge America.

Special musical guests for the event include Michael McDonald, Alison Krauss, Darius Rucker, Melinda Doolittle and Mac McAnally, with an appearance by New York Times best selling author Stephen Mansfield.

Tickets are priced at $50, $75 and $95 for general admission. A $500 ticket for Gold Circle seating includes a post-show reception. Public on-sales for the event begin May 2.

“Amy and Vince have been among our most ardent supporters,” said Houston Cowan, CEO and co-founder of Challenge Aspen and founder of Challenge America, in a statement. “What we hear from wounded warriors is their simple desire to find a new normal life — a job they can be proud of, a home, and recreational opportunities with their families in their own communities. We are delighted that Amy and Vince are hosting an event of this magnitude to launch our organization to help provide access to these opportunities.”
