Thomas Henden asked, "Does it seem that it really plays?  Do the keys
move?  Is the sound dubbed or original?"

The keys do really move, but they must have been rigged to do so.  As
the pianola was traveling down the road while playing, you could see
piano roll sometimes get caught by a gust of wind and flap around away
from the tracker bar without the music being interrupted.
