Most likely both.
I guess Sinatra and the Kennedy's even had connections to the mafia.
But fortunately, at least a couple of those recordings that were not put out were finally put out on cd.
Hell, they probably thought they would have dominated the scene too much.

But I was'nt even born yet when they came out.
It is just beyond me why the record company would'nt put it out from the little I have heard.
