Well there is the original Rod Stewart recording for Patch Adams and I believe three different versions of Where My Heart Will Take Me, the arrangement of “Faith of the Heart” that became the theme song for ENT.

EDIT: By three I mean, the theme version, a full length recording (which I am certain is a different mix) and a arrangement that Russel Willson used for a recording on a solo album.

EDIT 2: I forgot about the season 3 and 4 theme. Different arrangement.
