Oh say, did she see 50 states?

Janine Stange doesn’t get tired of singing “The Star-Spangled Banner,” even after singing it once an hour for 24 hours last weekend.

The 37-year-old Los Angeles woman performed the national anthem routinely from 5:30 p.m. July 31 to 5:30 p.m. Aug. 1 at Dana Hills High School in Dana Point during a 24-hour lacrosse game benefiting Shootout for Soldiers, a nonprofit that supports wounded veterans.

Stange, who ate bananas to keep her energy up, said pacing herself and taking it one step at a time was the key to making it through all 24 hours.

“I’ve sung this song hundreds of times and know how to pace myself,” Stange said after completing her 24-hour run. “I also know that the national anthem is not just my song, it’s our song. It’s not meant to be sung crazily. It has to be done so people can sing along and have a moment with this song.”

She said she came up with the 24-hour idea after being approached by Shootout for Soldiers for the event.

“I asked Janine to get involved with Shootout for Soldiers California through a Twitter recommendation,” said R.J. Kaminski, director of social media for the group, in an email. “Once I reviewed her profile and checked out some of her work on YouTube, my team and I knew she’d be a great fit.

“It’s funny. When she called me and said she had a great idea, I knew exactly what she was getting at. Before she even got the words out I said, ‘Let’s do this.’”

Each time Stange sang, a current soldier or veteran would hold an American flag. It was later auctioned off on eBay to raise money for the Gary Sinise Foundation, which supports veterans. When the auction ended Thursday evening, the flag had sold for $1,524.

The flag marks the first of 50 that Stange said she will auction off to represent the 50 states. She said that although she is not likely to sing for 24 hours straight again, she plans to sing in all 50 states for a second time. She completed singing the national anthem in all 50 states last year in a self-booked tour that she paid for through personal savings and $12,000 in donations.

She said standing with veterans and soldiers made her emotional.

“It deepens things for you when things like that happen,” she said. “I tried not to get too emotional, but it was hard.”

While Stange, who owns a graphic design and print company, said she has not served in the military, she got to know veterans and current members of the service last year when she toured the country singing the national anthem, earning her the nickname “National Anthem Girl.”

Stange also works with a nonprofit called Operation Gratitude by having fans write thank-you cards to soldiers at her performances. The cards are then sent as part of Operation Gratitude care packages. Those interested in participating can do so through operationgratitude.com.

“I met so many people who could relate to Shootout for Soldiers,” Stange said. “The way our brave men and women carry themselves, they deserve all the honor and respect that we can give them.”
