In pictures: The NFL Super Bowl XLVII
The Sandy Hook Elementary School choir sang ahead of America's biggest sporting event, The Superbowl.
In December, 20 children and six adults from the school were killed in a shooting rampage.
Singer Jennifer Hudson performed patriotic song "America the Beautiful" with the children ahead of the match between the Baltimore Ravens and San Francisco 49ers.
Beyonce hasn't given much away about her performance at half time during Sunday's Super Bowl - other than promising she'll be singing live. The singer admitted miming at Barack Obama's inauguration because she hadn't been able to rehearse properly.
She says there won't be a repeat of that in New Orleans during the game between the Baltimore Ravens and San Francisco 49ers.
As Beyonce makes final preparations, a clip has appeared online of one other thing she should avoid doing - handing the microphone to the crowd and asking them to sing along.
As a past performance proved, that can mean the song falls rather flat.
