Pokemon TV BGM

My question is whether anyone knows if the BGM for the battle itself (either 3 or 4 pieces in all) has ever been released? The fight is roughly halfway through the video. I have the music from the Season 1 OST and the collection with the Gold and Silver and Advanced Adventure seasons, but since this episode was in the end of season 1, it appears that it was skipped on those CDs. If anyone knows whether this music was released (and where I can find it), that would be awesome.
