Jerry,
Unfortunately the opening shot is typical. Hard drinking was his downfall. He drank his way out of career opportunities, friendships, and most other things in life. His only trusted companion in later life was his dog.
A local couple sort of took him under their wing and the guy, a plumber by day, used to drive Johnny to venues and accompany him on bass at night. His bass playing was pretty dire and Johnny used to call out the chord progressions to him in a very derogatory manner. One "fan" asked Johnny why such a great accordionist put up with a poor bass player. Johnny's answer was "Yes, he's crap, but he has a car!". That's how bad things were, and it was sad that he ended up the way he did.
His old Accordiola is still doing the rounds somewhere, treble buttons all out of alignment, missing bass buttons, cigar ash burns, the lot. According to the Jordaan folklore in Amsterdam his son, Cor, apparently sold it for drugs money when his father died, but it turned up again some time later. I've seen it being aired on You Tube once or twice, but cannot remember who the player was.
He actually won the title "Roi de l 'Accordeon" in Paris in 1953, but in later life couldn't even be bothered to speak about it.
Johnny Meijer. Yet another guy who tragically proved that the content of the bottle is often stronger than the constitution of man.
