From the interest shown by the passersby, I imagine the jams may spontaneously grow if they are held on a semi-regular basis. Word gets around. Even for this one, we had some drop-ins singing along on "Ripple" (and the parody) and on "Amazing Grace" and maybe a couple of others.

Also, Susan, Keith could've borrowed a guitar from one of us for a song or two. (Some of us were getting blisters, as it was.) Even if someone comes sans instruments, I'm sure they can find a way to join in.
