misericordia Hamilton Star Miguel Cervantes Sings And Dances With Misericordia Residents

Residents of Misericordia, an organization that serves adults with developmental disabilities, were treated to a live performance by Cervantes, who emceed the lighting of Chicago’s official Christmas tree in Millenium Park Friday evening.
