Sisters in Song, an evening of duets by Mary Rudolph, Paula Foukas and several other singers, many of whom are breast cancer survivors, will take place tomorrow at 7:30 p.m. at the Assumption of the Virgin Mary Greek Orthodox Church. Tickets cost $20 per person and may be purchased at the door. Refreshments will also be served. All of the proceeds from the event will be donated to the Ellie Fund, a nonprofit organization that fights breast cancer by easing its effects on patients and families. Each year, the organization provides critical support services, including transportation to medical appointments, childcare, housekeeping, groceries and nutritious prepared/delivered meals free of charge to hundreds of women and family members across the state. Additional donations are welcome; checks should be made payable to “Sisters in Song.” For more information, visit www.elliefund.org. The concert will be held in the church hall at 8 Lafayette Road in Ipswich.
