Song sheets available here, if you want to practice: http://files.meetup.com/1634379/ccae%20jam%202013.pdf
Our annual outdoor jam in Harvard Square. The folks at CCAE provide space and chairs and lemonade, so it's ez-in, ez-out.
We'll have song packets available day-of, or print out your own from the link above. (Mostly familiar songs that will be easy to play in a big crowd).
The weather's looking nice, so come on out and play!
