Need 18 bars of "God Bless the Broken Road"?

My 13 year old daughter is auditioning for a local play and has to do 18 bars of a song. She wants to do Carrie Underwood(?)'s "God Bless the Broken Road." I don't have/can't find any sheet music for the song to see what 18 bars to do! A little help? Thank you.
