'It may be a touchy subject, but let's touch it': Lady Gaga dedicates song to Marriage Equality

Lady Gaga and Tony Bennett continue their massively successful Cheek to Cheek world tour with a sold-out gig at Chicago's Ravinia jazz festival. According to Gaga herself, the concert was the fastest-selling show in the 111-year history of Ravinia.

During the show, Mother Monster dedicated a song to yesterday's historic Supreme Court ruling on marriage equality, which gave gay and lesbian couples the right to marry anywhere in the United States.

"I have to dedicate this song tonight to marriage equality," Gaga told the crowd before singing the Billy Strayhorn classic 'Lush Life.' She continued: "I know it may be a touchy subject, but let's touch it. Because — what a victory, what a special day for love. So this is for you, for fighting. And also for Tony Bennett, who fought for the civil rights of so many."

Gaga couldn't be more right about Mr. Bennett — the 89-year-old musician has been on the right side of history for all of his life, having participated in the historic Selma march with Dr. Martin Luther King in 1965 and helped liberate a Nazi death camp during World War II. In 2007, Tony was honored by the United Nations with its Citizen of the World award in recognition of his activism.
