Don Campbell’s Flotilla to Fight Cancer
1 p.m. Saturday. Water off Cow Island in Casco Bay. Donations to Maine Cancer Foundation appreciated. doncampbellmusic.com
Singer-songwriter Don Campbell is teaming up with WPOR 101.9 to present a live performance from a boat to raise funds for the Maine Cancer Foundation. Make your way in a boat or kayak to the waters near Cow Island, just past Great Diamond Island, and drop anchor/stay put. Campbell and his band will play a set of rock and country covers and originals, and you’ll also hear from the duo 12/OC and likely a few other acts. The goal is to raise $50,000, and you can make a splash by donating even if you can’t make it to show.
