I presume Macy's next move will be to try to lure the Boston Pops to New York on a future July 4th to perform "1812 Overture" and "Stars And Stripes Forever" to begin the fireworks display (since at the Boston concert, both are accompanied with fireworks) and to also make a major financial gift to the Pops' parent organization, the Boston Symphony Orchestra.
The idea of making a big $$$ gift to the Boston Symphony/Boston Pops might be an offer that the organization couldn't refuse, which Macy's might hope would end the almost four-decade tradition of a Boston Pops' July 4th concert and fireworks show in their hometown.
If that happens, some July 4th in the near future, the area around Boston's Hatch Shell might be empty and the skies over the Charles River would be quiet.
Don't bet against Macy's trying to lure the Boston Pops to New York for the 4th in the near future, as it may be the only way for the Pops to get back on national TV on the Fourth, even if it means the Pops "screwing" their home town (that's where the big-money gift would come in, so the Pops can't refuse the dollars).
By the way, I do recall that for the centennial of the Statue Of Liberty in the 1980's, the Boston Pops did play in New York on the 4th, but came back to Boston to do their traditional concert and fireworks show the next evening.
