One great song is "Just one step" From Songs for a New World sassy, sarcastic, fun, uptempo.
Another is "Climbing Up Hill" from The Last Five Years and that is uptempo, the singer actually makes fun of auditions so that would be fun.
"You want to be my friend" from "Closter than Ever"
"Whenever I dream" from A New Brain
"Listen to the song that I sing and trust me..."
