Guide Vocal CD

Hello, we are currently using the Reference Recording provided by MTI (Australian Live Cast) to choreograph and block certain scenes. However, the struggle is that the recording, although the most accurate, is far from accurate from the actual show in terms of scoring and other songs. We are trying to get a hold of a more accurate recording with vocals, and we have heard that you provide a guide vocal CD with your accompaniment CD. Is there any way to obtain this guide vocal CD without buying/renting the performance accompaniment CD? Thank you for your time.
