George Dennehy was born  without arms but amazingly has learned to play the guitar using only his feet.  On June 2, the 18-year-old performed a cover of the song "Iris" by the band Goo  Goo Dolls at theAshland  Strawberry Faire in Ashland, Va. Video  of that performance has been viewed by nearly half a million people on  YouTube alone and caught the attention of the band members, who invited Dennehy  to performed live with them at the Musikfest 2012 festival in Pennsylvania this  past weekend.

"I think people see the willpower and  determination and how much that performance meant to me and that song. I guess  it touches people's hearts," Dennehy said of his Virginia performance during  aninterview with  What's Trending host Shira Lazar.

And as if that weren't amazing enough,  Dennehy tells Lazar that he's actually a multi-instrumentalist, playing the  piano, bass and cello—all with his feet.

"Every person has their purpose here,"  Dennehy said. "We're all here for a reason. Don't let anything get in someone's  way to do what they feel called to do. I just want people to see that even  though I don't have arms I'm still striving to do what I want to do in my  life."

Here's a video of Dennehy's performance  with the Goo Goo Dolls.
