Classic Sesame Street Cover: "Up Goes The Castle"

Normally, a guided meditation on breath control is something adults expect to hear on a New Age yoga CD...not an old Sesame Street album.  Hearing this song, with its kid-friendly imagery and story, might change those people's minds though!  I discovered this fan-made performance while uploading my own clips to YouTube...if anyone can tell me which album the original version was on, I'd appreciate that a lot.  Thank you!
