Fans have about 16 months left to catch Garth Brooks in North America, but the singer isn't ruling out more shows, after he explores a few other countries.

Prior to his show at New York City's Yankee Stadium on Friday night (July 8), Brooks explained that there are about 20 North American cities left, and he'll wrap around November 2017. Then he'll head overseas.

"The guys from Australia came up and talked to us, they were very sweet," Brooks tells Taste of Country. "And of course, Europe we (Brooks and Trisha Yearwood) could probably trade places in Europe. They worship her over there and should."

The tour began in September 2014 with a series of shows in Chicago, and he's continued to play about two cities a month since then. When he's done overseas, he says he's open to playing some special events, like the Houston Livestock Rodeo.

Meanwhile the superstar and Country Hall of Famer continues to work on music for a new album, his second since coming out of retirement. During a separate interview with ToC, Yearwood revealed that her Christmas album with Brooks is finished, but she didn't go as far as to say it'd be released in 2016.

After New York City, Brooks has just two cities on his itinerary: San Antonio, Texas and Bossier City, La. He shared that on Monday he'll begin a series of Monday night Facebook live broadcasts that will take fans in studio with him as he works on new music.
