It's a "circus comes to town" atmosphere at the Common this afternoon. Like a few people I spoke to who heard a little "Let it Be" piano, I went for a quick peek. No Paulie, but there are tons of people on the Common, soaking up sun, lounging in lawnchairs, snapping photos and playing frisbee. There's even a group with a guitar and a Beatles songbook knowledge, entertaining everyone. There's still quite a bit of the Common that's accessible, and there are even drinking fountains, if your voice gets harsh after your sixth rendition of "Strawberry Fields Forever."
