“Romeo vs. Juliet” at 6:30 p.m. Friday; noon and 2 p.m. Saturday; and 2 p.m. Sunday at Joan Lorentz Park, in front of the Cambridge Main Library, 449 Broadway. Free.

As baseball season gets into full swing, Anthem Theatre Co. presents an all-ages hourlong baseball rivalry-inspired vaudeville comedy version of Shakespeare’s classic, adapted by Johnny Kinsman and directed by Bryn Boice. “The conceit is that Juliet is the star pitcher for the Capulet team and Romeo is the Montague team’s hottest hitter. They meet in a fateful at-bat,” she told BU Today. The production is being staged tonight through Sunday and again next weekend, June 26 to 28. The play promises to strike out (get it?) the romantic tragedy and pitch (and this?) some old-time song and dance, and you should prepare yourself for such bits as Coach “Friar” Lawrence doing a rundown of “Who’s on First” too. Information is here.

From estimates of 5,000, crowds in years past hit 10,000 and then 12,000 people and now 20,000 people are expected to dance at this year’s street party to DJ-spun music (and, after dark, a light show). Find out the details and five things to love about the dance party here and get information from the city here.
