That is one awesome prop! Wow, and what a bargain! It looks so expensive the way you 'refurbished' it. And I agree with Roxy, I love the choice of music and your organist! Very creepy, but very cool. Take a bow sir!

The other row(s) of pipes can be mounted on a shelf or extended deck. Actually, they could just be a separate component that is pinned between the organ and the wall.
It would be great to get a player piano mechanism to be able to have the keys move as the music is going, regardless of whether the key movement matches the music or not.
