I asked Peter about the Stereo drums if he had the original multitrack recordings and he said he only used a few mics to record them.

You can get something like EZDrummer 2 but you can't make your own track as it won't send the song position pointer to the VSTi so it just loops on bar 1 but it will play the BB midi drum track.
