CHICAGO (CBS) — GiGi Gianni,16, sang National Anthem before Tuesday night’s Cubs game at Wrigley Field.

She’s the inspiration for GiGi’s Playhouse Down Syndrome Achievement Centers.

GiGi’s mom Nancy says GiGi has always loved the National Anthem but worked for seven years to articulate the words and practices every day in order to sing it in front of nearly 40,000 people.
