**Lady Gaga and Tony Bennett brought their Cheek to Cheek world tour to Detroit's Meadow Brook Hall on Monday night and treated the sold-out crowd to a night of classic selections from the Great American Songbook, including such beloved standards as "Anything Goes," "Lush Life" and "It Don't Mean A Thing." Gaga, however, had to briefly stop the show to calm down an enthusiastic fan, who had been waving at the singer and taking photos non-stop. "I’m gonna let you take one selfie, and then you’re going to listen to the music," Mother Monster told the fan, and, after kneeling down to take that selfie, added: "My whole generation is high on their cell phones."
