Remember the Rare Essence 7-inch mentioned on Arts Desk yesterday? Adams Morgan vintage shop Joint Custody is giving away copies of a single by the classic go-go band for free, as part of its Record Store Day happenings tomorrow.

“It is just stock copies of an old Rare Essence release,” writes co-owner James Ritter in an e-mail. “We just figured we’d give them away as a way to promote local music and to give people a chance to hear good local music for free as opposed to lining up to purchase manufactured rarities. They are just a gift from us to our patrons. We have no affiliation with Rare Essence aside from loving their music. We just happened to have a bunch of copies of one of their older records.”

Ritter writes that the free vinyl is “probably” the 1982 “Body Moves” single, which was produced by Chuck Brown and Jas Funk. Update, April 21: It’s the “Back Up Against the Wall” single.

The first 50 customers in the store on Saturday will receive the 7-inch. Joint Custody will also have a root beer keg and free candy in the store tomorrow, in addition to select Record Store Day titles and a 10-percent-off sale on used records.

Joint Custody is open from noon to 11 p.m. tomorrow. 2337 18th St. NW.
