Lexington-bred actress/comedian Rachel Dratch has been tweeting from rehearsals for “Love’s Labour’s Lost,” a new musical adaptation of the comedy that will debut at Shakespeare in the Park, New York City’s version of our Shakespeare on the Common. The production, by Michael Friedman and Alex Timbers of “Bloody Bloody Andrew Jackson” (which was recently performed by Boston’s SpeakEasy Stage Company), will feature Dratch as a version of Shakespeare’s school teacher character Holofernes. Dratch tweeted Monday, “Having so much fun rehearsing for Shakespeare in the Park! Previews start July 23, good sirrahs! Shall I see you there ’pon the morrow?” Here’s hoping she joins Commonwealth Shakespeare Company for a show on the Common next summer.
