I was able to find an example of newspaper ad that was running at the time. See below..
In an odd way this was starting to make sense. I know that it would be expected that The Happy Terrorist would follow in his father's footstep and continue the family tradition of making high quality explosives but it seems that The Happy Terrorist would rather sing, dance and fly kites. The very fact that he did not follow in his father's footsteps would bring great shame to the family and most likely place a bounty on The Happy Terrorist's head.
Will he ever get the chance to dance in "Jersey Boys"?
I'll have to look into this some more....
