Greyson Chance attends the 2011 US Open Opening Night Ceremony at the Billie Jean King National Tennis Center on Monday night (August 29) in NYC.

The 14-year-old musician, looking cool in a black tie, and a gray shirt tucked into jeans, sang the national anthem at the ceremony.

The next day, Greyson headed up north to Toronto to perform at the Canadian National Exhibition for Cambio.

Greyson recently shared with the JJJ Book Club some thoughts on his favorite book, “Looking for Alaska.”
