Producer
A.k.a. Pierre Culliford
Pierre Culliford is largely known to the world as Peyo, creator of the Smurfs. Peyo played the manager of The Bowling Balls in the fake interviews they gave, before the band even existed. Who Jack Grodikski the producer really is, is only known to the members of The Bowling Balls themselves, but we can surely say that Frédéric Jannin, keyfigure of it all, is a fair candidate.
