I missed it last night..thinking it would be on the 4th.
Yes. they moved it up because of the impending storm.
My Dad (RIP) took all of us to the 1976 Bicentennial Concert which was, Of Course, Arthur Feidler. It was wonderful, and there were over 500,000 people there. They did the whole 1812, and you could have heard a pin drop in the audience. It was a transcendent experience, and i will treasure it always.
Maybe that is why I am so sensitive about this beautiful Boston tradition, and get very disgruntled when it is done poorly.
