I found this in an old TV magazine from the 1950s. It features a small profile of a 15-year-old named "Mickey Braddock," who starred in a short lived series called "Circus Boy." It was about a circus clown who adopted a young orphan, and took him on the road trip of a lifetime. 

It only ran about a year in the mid-50s and was quickly cancelled. In the precis of the "new" show, Braddock indicated he hoped to have a long acting career when his first show came to an end. But he could never have dreamed what would come next. 


So what happened to him? He dropped the "E" from his first name and began using his real last name. And the next time he was heard from in 1966 was not only for his acting voice but his singing one. Mickey Braddock was really Micky Dolenz and he became one of "The Monkees." 

Now in his 80s, he's the last surviving member of the group that had a ton of hits during their brief run. He still tours today. 

 

(Notice that in the 1957 ad above, WGR-TV was then an ABC affiliate.)

This would have been the second season premiere. NBC aired season one in 1956.
