Forty-six gay couples exchanged vows against the backdrop of Niagara Falls on Monday, a day after New York became the sixth and largest state to recognize same-sex marriage. The newlyweds wore matching tuxedoes and suits for the 30-minute ceremony, which opened with a playing of Ray Charles singing “Somewhere Over the Rainbow.” The group wedding came as hundreds of same-sex couple across the state and nearby states began getting married Sunday, the first day New York allowed them.
