The Mount Auburn Hospital will host its 17th annual music fest to raise funds for the Cambridge medical center’s future healing garden next Sunday at the French American Victory Club on Elm Street in Waltham. The event will feature musical performances by Kelli Trottier, Amy Gallatin and Stillwaters, and the Special Guesters band, consisting of guitarists Chuck Parrish and Jim Spellman, violinist Matt Leavenworth, and Edmond Boudreau on mandolin. All of the proceeds will go toward building a healing garden at Mount Auburn Hospital. The fund-raising festival was started 17 years ago by Terry Eagan, a longtime Waltham resident, to help fulfill his wife Mary’s dream to build a healing garden for patients suffering from cancer. Mary passed away from leukemia in 1992. Since then, Eagan has used these music festivals to help fund and build healing gardens throughout Greater Boston and Canada, including one named for his wife at the Boston Children’s Hospital facility in Waltham. Tickets for Sunday’s event cost $17 in advance or $20 at the door, and are available online at www.patiorecords.com or in person at Marcou Jewelers, 318 Moody St. Doors will open at 1:15 p.m., and the show will begin at 2 p.m.
