Are any of Jerry Lewis' children in the movie business?

I assume you mean the comedian and humanitarian. One of Lewis" sons died in childhood, this may have spurred Jerry on to his work with Muscular Dystrophy. Another, I can"t recall his first name - maybe Gary Lewis, had a rock group called the Playboys- they had one major hit- This Diamond Ring. There was another group called , I seem to recall from old Juke Boxes- Johnny Fred and the Playboy Band, shortened to Johnny Fred and Playboys- on Juke-box labels. Neither had any connection with the famous Girly magazine.
