The only other time Gaga had performed “ Summerboy ” before Wednesday night’s Mayhem Ball show was during a performance at Lollapalooza in 2007, where she played the song in panties and black stockings. It was well before her first single, “Just Dance,” and her album The Fame, which came in 2008.

On Wednesday (July 16) night at Las Vegas' T-Mobile Arena (technically in Paradise, Nevada), Lady Gaga ushered in a new touring era, officially kicking off the Mayhem Ball (in support of her Billboard 200-topping album Mayhem, naturally) to a sold-out crowd.
