BANGOR, Maine — Waterfront Concerts promoter Alex Gray said Sunday that he doesn’t plan to call off Ted Nugent’s Bangor performance despite remarks from two city councilors that the controversial rock star shouldn’t be allowed to play in the city. Last week, Councilor Charlie Longo emailed a letter to Gray saying that the concert series shouldn’t allow Nugent to perform because of comments he made during a National Rifle Association convention in St. Louis. Longo later posted the letter to his website.
