SAN FRANCISCO (AP) — A Britt has helped to kickoff the NFL season. Ellie Goulding headlined the free NFL Kickoff 2015 concert in a park in downtown San Francisco yesterday. To her, football is what Americans call soccer. So, she studied-up on the American game prior to the show, which included her hit “Burn.” Train was also on the bill. The concert was in San Francisco because Super Bowl 50 will be in the San Francisco Bay Area.
