HELP ME!

My name is Josh and I am 17 years old. I am a senior in High School and happen to be part of a show choir there. We annually perform our "Country Western" show in the spring and as a member, I am allowed to choose a solo act to perform. I have chosen Michael's "I will Whisper your name". My dad sang that song to my stepmom when they were married, and I really would like to sing it for the show. What I need help with is the track. I HAVE TO FIND the track to this song. I just need the music and the backup singers, and no words. WHERE CAN I FIND THAT?
