Does anybody remember a Batman TV show episode where Liberace played two
parts as a concert pianist and his evil twin brother.  Their headquarters was
in an abandoned piano roll factory.  There was an Ampico reproducing piano
and a rare J P Seeburg style J solo orchestrian.  The evil brother tried to
run Batman and Robin through the music roll perforator.  As they went through
Batman hummed a tune that would cause the perforator to only cut holes around
their bodies and not harm them.

Does anyone know where the studio borrowed the machines or who they
belonged to?

Also what year the show was made?

It had to have been about thirty years ago when I was just a kid but I really
was interested in it even back then.
