Penn State dance groups Rince na Leon and the Penn State Dance Alliance took to the THON stage in a 27-minute dance break.
In its first appearance at the Interfraternity Council/Panhellenic Dance Marathon, the Rince na Leon women performed decked out in black leotards, tights and blue skirts, featuring their traditional Irish dance moves.
Rince na Leon performed twice, with the first set featuring the whole group then a shorter performance featuring eight women.
The second portion featured a traditional Irish dance, but surprised the THON crowd when the group broke out some Irish dance moves to the Swedish House Mafia hit "Don't You Worry Child."
Rince na Leon started two years ago in the spring and provides "an opportunity for retired, non-competitive, and competitive Irish Dancers to dance at Penn State," according to the group's official website.
Rince na Leon posted on its official website earlier in the day about the opportunity to perform at THON for the first time.
"We feel so lucky to have this opportunity and can't wait to help support this great Penn State tradition!!!" the group posted.
Penn State Dance Alliance took to the THON stage in between Rince na Leon's performances.
A dance-pop mix including "Lights" by Ellie Goulding, "What Makes You Beautiful" by One Direction and "Some Nights" by recent Grammy-award winner fun. suplimented the group's mixture of choreography, spotlighting hip-hop and ballet.
