Hoping to get Chicago Cubs fans pumped up for opening day back in April, Lisa Johnson McFarland put her own spin on the fan favorite "Go, Cubs, Go" with her gospel-trained singing voice.
Her song has since been viewed more than a million times on Facebook, and now McFarland is hoping to perform an encore as the Cubs try to win their first World Series in 108 years.
"We believe,'' she told TODAY. "This is the year."
McFarland, 51, worked in corporate America for around 20 years before deciding to take a step back to pursue singing, billing herself as "Lisa the Psalmist."
Encouraged by her sons, Brandon, 32, and Byron, 28, the mom from Lockport, Illinois, decided to break out a singing voice she had previously only shown off in church.
"My first love has always been singing,'' she said. "I had my children and put my dreams on the backburner. I was thinking, 'Oh, you're too old,' but my boys are saying, 'Mom, you still have it.'''

McFarland's husband, Clifford, 68, who is retired from his job with a petroleum company, is a diehard Cubs fan. He has since converted her into one during their 24-year marriage.
All that's left now is for the Cubs to finish the job. They are the odds-on favorite to win their first World Series since 1908 after leading Major League Baseball with 103 wins in the regular season.
They are getting set to start the National League Championship Series on Saturday against the Los Angeles Dodgers after knocking off the San Francisco Giants in the divisional round.
One Giants fan brought a goat to Game 4, referring to a legendary curse that was supposedly put on the Cubs in the 1945 World Series.
The owner of the Billy Goat Tavern was asked to leave Wrigley Field during a World Series game and allegedly cursed them to never win it again.
Despite the jinx attempt this year, the Cubs came back to beat the Giants in that game.
"They have the goat, but that's OK, (the Cubs) have me,'' McFarland laughed. "I'm the secret weapon."
