Is this song okay to sing in a audition?

Well, I think "Ten Minute Ago" from Cinderella would be a lot more appropriate, considering it's more of an upbeat love song. And I'd think it'd be perfect for a Fiddler on the Roof audition :) I used that song when I was 14 for "Into the Woods", I got a solo part out of it :) So I'd think it'd be a great song choice for you to, since you're 14 aswell :) Just make sure you have all the parts down, and you can pretty much sing it in the car, in your sleep. Because if you know it like that, at the back of your hand. You'll be able to sing it anywhere :) Good luck and have fun :)
