You’re invited to the third waltz of the season. Tina Chancey, Liz Donaldson and Ralph Gordon, aka WALTZ SISTERS, will provide dance music in Glen Echo’s Spanish Ballroom. Suggested donation of $15 per person ($5 for students and children), to compensate the band and sound tech and pay the room rental, will be collected at the door. Beginning waltz lesson starts at 2:45. Music from 3:30-6:00 p.m. Put on your dancing shoes–they’ve been dormant too long!
