POLAND — The Poland Spring Preservation Society will welcome Sidecar Heroes, an energetic a cappella group, on Monday, June 21, at All Souls Chapel.

The 7 p.m. performance is part of the society’s summer concert series, which runs every Monday through Aug. 30.

Sidecar Heroes is made up of six men who combine tight harmonies and rockin’ rhythms with an eclectic repertoire of rock, doo-wop, funk, motown and more.

All proceeds benefit the preservation and restoration of the Maine State Building and All Souls Chapel, both of which are listed on the National Registry of Historic Places. Proceeds also help fund the society’s educational programs.

Tickets are $7.50 at the door and include refreshments. For more information, call 998-4142 or visit www.polandspringps.org.
