Castle Singers alumni reunions are not held on a regular basis at this point. However, there have been two successful reunions recently. The 2006 reunion participants performed with current Castle Singer students for the 2006 Homecoming Kastle Kapers variety show. In 2004, a "Down Under" reunion was held in the Quad Cities for alumni from the 1994 and 1998 Australian tours. Activities included a dinner on Friday night at the restaurant, Old Chicago, in Bettendorf, and a barbeque held at the Yeager home on Saturday evening.
