‘I Wish’ (1995 unproduced film version)

Does anyone know if there’s anywhere I can listen to the full demo of ‘I Wish’ written for the 1995 attempted film adaptation of ITW? All I can find are the lyrics, and a short section of the demo in a YouTube video about the film (https://youtu.be/gKZEld3e8PU?t=819&si=TB8x8ZyQm2tBVR7q). If anyone has it, or knows where I can hear it, please let me know!
