The Medford Public Library welcomes Judah Leblang to perform “The Expiration Date,” his poignant and sometimes humorous look at life’s transitions: getting older; dealing with faith and the lack of it; trying to outrun Father Time; and wondering what, if anything, comes next. Prepare to be entertained and stimulated as you watch one “Junior Senior Citizen” wrestle with life’s big questions in this one-man show. Registration is required through the library’s online calendar.
