The Double Edge Theater put on a fantastic Latin American Spectacle show in the soaring vaulted hall of the former Blessed Sacrament Church this past Saturday and Sunday nights during Memorial Day weekend. The show was part three-ring acrobatic circus, part political theater and part High Mass. The ensemble of musicians and dancers from Charlestown Working Theater and the Hyde Square Task Force put on a story-song about a community in change. The audience was part of the performance although the audience weren't quite aware of that during the Sunday evening performance. The program began with a costumed vocalist singing traditional songs with her accompanying guitarist standing on the church steps. Then came two costumed women, mother and daughter, circulating with bunches of long stem flowers that the younger one gave away; Following them was a merchant in dark suit coat and flowered fedora pulling a kiddie wagon with samples of his wares, working the audience with jokes and comments as his assistant gave away watermelon slices saying "eat it quickly" as he warned one tyke "or it'll melt."
