The thing I found interesting about this event was the sheer determination on the part of the hosts not to place emphasis on "Haves vs. Have Nots" - about a quarter of the people in attendance were volunteers...who obviously hadn't any Thanksgiving dinner yet - it was 11 in the morning after all. So just about everyone was interested in eating. Not just the "less fortunate."
They thought of everything except music. So people (full and happy people) started making music of their own.
A few hours later, everyone left. Some to attend to their families, others to their memories of an unusually warm Thanksgiving Day.
