“‘Riverdance,’ I guess, put Ireland on the map, I guess 20 years ago, and it’s great to be carrying that around the world,” said James Greenan, one of the principal dancers in “Riverdance: The 20th Anniversary World Tour.”

Greenan started dancing at age 10.

“My mother kind of pushed me into it,” he said.

“The same as James. I was forced to lessons, absolutely forced,” Ciara Sexton said.

Coloradan Greg Molony was mesmerized at age 5.

“The PBS special came on of ‘Riverdance’ and I just looked at my parents and said, ‘That’s what I want to do,'” Molony said.

Molony is a graduate of Grandview High School. He joined the “Riverdance” tour two weeks ago and says he was a bit nervous at his first performance.

“I was just like, ‘It went really well,’ and turned to the trash can and threw up,” he said.

“Riverdance: The 20th Anniversary World Tour” runs through March 13 at the Buell Theatre. Get tickets and show times at denvercenter.org.
