There was this guy called Stefano.

Haphazardly he stumbled across that secret backdoor swing party somewhere in Downtown Chicago (but this never took place - the gatekeeper now sleeps with the fishes...). Accidentally he brought a camera along with him. 

By sheer chance he pressed the record button while the objective had it's stochastical sight on a very special live performance of the Billy Rubin Trio and the beloved Patentochter of the Don, Lady S.

He now happens to be a VERY close friend to the family.
