The Royal Canadian Artillery Band will perform its fifth annual Christmas concert, A Christmas Wish, tonight at the Winspear Centre. The band will perform alongside the Richard Eaton Singers, a symphonic chorus directed by Dr. Leonard Ratzlaff, as well as vocalists Christian Mena and Kelly Alanna. The performance is a salute to Canadian troops and is also a fundraiser for the Make A Wish foundation for northern Alberta. All proceeds from ticket sales will go towards granting magical wishes for children with life-threatening medical conditions. Tickets are $10 for adults, $5 for children, and are available through the Winspear box office or by phone at 780-428-1414. The show starts at 7 p.m.
