Jewschool has the story:
According to a full-page advertisement in The Forward, available as a pdf here, New York Senator Charles Schumer will be making a “Special Appearance†at an event in Central Park that apparently opposes a two-state solution, is opposed to negotiations over Jerusalem, refers to settlers as “heroic pioneer families,†insists “No! To The Surrender of Any Part of Israel,†and commits the cartographical catastrophe of depicting a map of Greater Israel, complete with annexed Territories, in the form of a guitar that stretches into Syria.
The rally, called the Israel Day Concert, is a radical alternative to the Salute to Israel Parade, which takes place a few yards away on the same day. The two events are unaffiliated, and the Concert is right-wing and mostly Orthodox while the parade is nominally apolitical. J.J. Goldberg describes the 1994 Israel Day Concert in his book Jewish Power as a “noisy anti-Israeli government rally featuring speeches by the hardline ex-general, Ariel Sharon, [the description fit in 1994] and a string of Orthodox militants.”
The Salute to Israel parade has yet to announce the politicians who will be in attendance, and a staffer there said that Schumer had been invited but had not officially confirmed. We’re waiting to hear back from Schumer’s office on whether he plans to attend both events.
