I was amazed to see the young kids playing 4-hands piano on Jim Neher's
link to Berks Piano Quartette [160918 MMDigest].  I am nearly 80 now
but as a child of about 10 I discovered that I could play piano by ear,
and pretty well.  I had a first cousin that also played, and we
discovered 4-hands piano.  We amazed our friends and adults with our
music and entertained for many family celebrations.

Later, I studied piano and learned to play by note.  After having a
stroke, I moved to a retirement village, where I got stroke therapy
and eventually recovered my right hand well enough to play some piano
again.  I called my cousin and proposed that we do a 4-hands concert
here.  We scheduled it to happen two years ago but he had cancer and
did not make it to the date scheduled.  The concert was cancelled.

In the meantime, not sure of how well I would recover, I decided to
build a carousel organ.  I have now built two of them.  One is a
Castlewood 20 pipe organ, and the second is an 87-pipe MIDI organ.

Thanks to Jim for posting the link to the kids playing 4-hand piano. 
I relived my youth playing with my cousin who I miss so much.
