You wouldn’t know it if you hung around City Hall, the city’s economic development team or even the Chamber of Commerce, but the City of Falls Church played host to one of the Washington, D.C., metropolitan region’s classiest galas Sunday night, the so-called “Wammies,” at its State Theatre. This is the regional equivalent to the national “Grammy” awards, bringing the cream of the crop of the area’s creative music scene right into Falls Church. The State Theatre was packed to the rafters and so was the Ireland’s Four Provinces restaurant a half-block away for the after-party. In fact, a handful in Falls Church officialdom knew of it. Vice Mayor Lindy Hockenberry was there and another prominent citizen scored a gig working security.
