Jonathan Groff, aka Kristoff, talks 'Frozen 2' ballad and singing karaoke with Idina Menzel
Elsa, Anna, Olaf, Kristoff and Sven are back!
Elsa, Anna, Olaf, Kristoff and Sven are back in the highly anticipated "Frozen 2."
Kristoff himself, aka Jonathan Groff, stopped by "Good Morning America" Friday and said he attended the movie's premiere with his young nieces.
"I was a little nervous because it's a big movie with big music and big action scenes and they didn't blink during the entire thing," Groff told "GMA." "They were on the edge of their seats, loved every second of it."
In 2013's "Frozen," Groff sings a short song, "Reindeer(s) Are Better Than People."
But in "Frozen 2," Groff performs his own ballad alongside Sven the reindeer.
"Bobby and Kristen Lopez, who did the music for the first film, wrote Kristoff this epic kind of 80s ballad and the animation that goes with it. It's like an 80s music video," Groff explained. "It's a joke for the adults. The little kids don't really get it."
In addition to singing in the film, Groff recently performed karaoke with Idina Menzel and Josh Gad, both of whom are reprising their roles as Elsa and Olaf.
"It was 1:30 in the morning at a gay bar in London," he said. "Idina did a surprise set. The bar is called Heaven and it really was my idea of heaven. [Josh Gad] brought the vocal. He really let it loose."
Groff also sang a duet with Kristen Bell. It was cut from the film, but added to the deluxe edition of the "Frozen 2 "album, he said.
"Frozen 2" is in theaters now.
