St. John's-native Tina Maddigan Mayer is scheduled to sing the Canadian anthem in Kansas City Friday night with the Royals hosting the Toronto Blue Jays in Game 1 of the American League Championship Series.

Maddigan Mayer, who just recently relocated to Missouri with her husband and young family, made the announcement Thursday on Facebook.

"My Canadian roots are proud to be singing the Canadian national anthem for the ALCS game," she wrote.

Maddigan spoke with CBC News by Skype on Friday afternoon and despite her many years of performing on some of the biggest stages, admitted to being nervous.

"It's just thrilling to be able to get to sing," she said.

So how did Mayer get this gig?

A friend of hers in Kansas City asked her recently if she knew the words to Canada's anthem.

Maddigan gave him a sarcastic reply, and was then asked if she would be interested in singing at the baseball game.

"Yes. I can," she replied without any hesitation.

The Royals offered her the opportunity, and tickets to the game for her, her husband and their two young children.

She has performed the anthem at sporting events before, but never on such a large stage, and before her "beloved Blue Jays."

Canadian baseball fans have been whipped into a frenzy in recent days, and Maddigan said she is honoured to be involved.

Maddigan Mayer is a graduate of Brother Rice High School and became a Broadway star after landing the lead role of Sophie in Mamma Mia, a mega-hit musical in New York.

She also played a leading role in the original Broadway production of The Wedding Singer
