WHAT CAN YOU GET for $50 these days? That will impress your loved one, that is? Well, get in touch with the a cappella group Capital Accord Chorus, and $50 gets you two songs sung by a quartet of the group’s singers, chocolates, a card and a digital photo after the fact as a memento. This Friday and Saturday, the chorus’s quartets will venture around the D.C. area, mostly inside the Beltway–but ask! A lot of the group’s slots are already spoken for, but they’ll try to accommodate everyone. To book them or just get more info, call 301-391-SONG (7664) or email firstname.lastname@example.org.
