POLAND SPRING — Virtuoso pianist Phil House and vocalist Kathy Haley will perform with special guests Sweet Sixties on Monday, Aug. 20, at All Souls Chapel.

The concert, part of the Poland Spring Preservation Society’s summer concert series, will begin at 7 p.m.

House is organist at the First Universalist Church in Auburn and has been playing at All Souls Chapel for more than two decades. He has performed concerts from Auburn to Nashville to Vienna, Austria.

Haley, who has also been playing the chapel for many years, was one of the lead singers in the group Good & Plenty. She is organist/choir director at Court Street Baptist Church of Auburn.

The Sweet Sixties trio — Haley, Joanne Demers Fuller and Susan Foisy McKenney — is a reunion of singers originally from Auburn. In their teen years at Edward Little High School they were members of the folk group The Chord Majority. That popular group also included Denny Breau, Ken Ford and the late Tom Rowe.
