<P> Singing their greatest hits as part of their act , they were also featured performing specialty numbers such as the frantic `` I Love a Violin '' , the a cappella `` Danny Boy '' , and a segment during which Phyllis retired backstage as Christine and Dorothy shared the spotlight playing a concert arrangement of `` The Way We Were '' on twin pianos . Other highlights in the act were a comical Trinidad - flavored tune , a soft rendering of `` Memory '' from Broadway 's Cats , and a `` Money Medley '' , which they also performed live on the Jerry Lewis MDA Telethon in 1994 . Since then , the sisters had made occasional public appearances together , including in 2004 , when they reunited to perform in a PBS special Magic Moments : Best of ' 50s Pop . The sisters ' command of their vocal cords and harmonious blend had not significantly diminished . </P>
