Broadway jazz musicians happy playing outside - worried about the winter coming

BBC reports from the parks of New York where jazz musicians usually playing at Broadway have found their new stage to perform. They, for a change, play together, as opposed to practicing alone at home, and they manage to earn something, hopefully, more than change. But, they're worried because the winter is coming, and it'll get different - it will be harder to play, and the audience won't be that eager to be outside, especially for longer than one song.
