The actual title of the song is "The Betrayal" and it has an interesting history. It can be had on eBay on CD, by the way. If you would like to host an MP3 of it ripped from the CD, email me.
"Toymaker's Dream" was a stage play based on a street drama called "Toymaker & Son"... read all about it
here. The soundtrack to the play had music from many of the top CCM artists of the time... Sherman Andrus, Matthew Ward, Bryan Duncan on keyboards I believe, Bob Carlisle, even Bob & Jayne Farrell on BGVs or something. Lots of great music. The stage performances went on for 16 years. At some points they were actually touring two completely separate productions of it simultaneously. They went to Russia during the Cold War, and to many other countries around the world... there are no spoken parts (the narration was on the soundtrack) so all they had to do was translate the narration and record a new voice-over and they could take it anywhere.
Anyway, back to that song. Over the long history of the show there were some changes to the soundtrack, and one of them was that song. Originally it was a completely different song, sort of along the same theme but featuring
only Matthew Ward. Seems to me that the title was "Money" or something like that. There is actually a version of the cassette soundtrack in existence with that older song on it, but I don't happen to have it in my collection. Don't know if that original version of the production was ever available on VHS (I think it was, but I'm not sure... the cover was black instead of the white they used later). That version also featured, if I remember correctly, Keith Green's song "The Victor" at the end; it was replaced with a song that had the same feel and same theme but presumably not the same royalty requirements.

I don't know why the Matthew Ward song was redone, but the middle part where Matthew sings ("Oh my Father, I need to know you're near...") was actually taken directly from the original recording, which explains why it sounds a little different. I think the new song is very effective; the Judas' plot is swirling around Jesus, but then He gets a quiet moment in Gethsemane to speak with His Father. The original version was pretty rockin' too, but I think maybe the hybrid version works better dramatically.
You ought to rip the actual video of the song... it's pretty cool stuff.
Here's the blurb about it from the ministry that was behind the stage production (actually, Impact was basically built by that stage production, although they have since moved on to newer projects):
