A big fan of pump organs, I now own three in my home of differing sizes, have owned and repaired another... three or four? They blend better with voice and guitar than piano, are usually free if you don't mind fixing them up some, never need tuning, can be carried much easier than a piano, sound so much nicer than anything electronic.

A song I wrote specifically for my big organ:

I more often stuck one in the background as orchestral filler:

T. Nathan Roane - Composer - 04 Arabic Blues

You've got an organ going there, no wonder the sound has so much body.

ComposerNate has great body and his organ is truly something to behold.

Highlights a common problem with museums--taking in new materials is work and costs money, so they really can't just take in any old whatever that comes their way.

The country church I went to as a kid had one of those pump organs. Unfortunately, it was a Catholic church, so the music sucked.
