5th Annual Ukulele Jam Happening in Harvard Square

Here’s something to check out if you’re in the Harvard Square area Friday evening. For the fifth year in a row, the Cambridge Center for Adult Education will host the Uke Jam, a free outdoor ukulele jam session.

BYO ukulele or just stop by and enjoy the performance. Uke teacher Danno Sullivan and others will play hits from as far back as 1910 to as recent as this year.

Insert Zooey Deschanel joke here.

Free, Friday, August 1, 7-9 p.m., Cambridge Center for Adult Education, 42 Brattle St. Courtyard, Cambridge.
