The Unitarian Universalist Church of Medford will be the site of a first reading of “An Infinity of Stars,” a new political musical comedy for our unsettling times. The show features a stellar cast of performers: Lydia Harrell, Cassandre McKinley, Will McMillan, Rene Pfister, Debo Ray, David Scott, Didi Stewart, and pianist extraordinaire Alizon Lissance. They will perform the complete original script and a 20-song score. Tickets are $20 through Eventbrite. Event organizers ask that audience members wear masks for the safety of immuno-compromised theatregoers.
