Circus Boy

Circus Boy is an American adventure family western that aired in prime time on NBC, and then on ABC, from 1956 to 1958. It was then rerun by NBC on Saturday mornings, from 1958 to 1960.
Summary.
Set in the late 1890s, the title of the series refers to a boy named Corky. After his parents, "The Flying Falcons," were killed in a trapeze accident, young Corky (Micky Dolenz – billed at the time as Micky Braddock) was adopted by Joey the Clown (Noah Beery, Jr.), and the whole Burke and Walsh Circus family.
The young boy quickly found a role with the circus as water boy to Bimbo, a baby elephant whom Corky would come to consider his pet. Riding Bimbo's back, Corky dealt with adolescent problems, and helped the show's adults including Joey, owner/promoter Big Tim Champion (Robert Lowery) and head canvasman Pete (Guinn Williams), keep the circus successful as the traveling show moved from town to town each week.
Outside of an elephant being the animal companion, the series was similar to popular "boy and his dog" shows of the time, such as "Lassie/Jeff's Collie", and "The Adventures of Rin Tin Tin".
Unusually, the opening credits billed the regular actors by their character names, rather than their own names.

References in "The Monkees".
Micky Dolenz sings the theme to the series in "The Monkees at the Circus", an episode of "The Monkees". When asked by Mike Nesmith "What 'is' that?", Dolenz responds "It's the theme song for an old TV series".
Their song "Porpoise Song" contains references to the series, most notably with the line "riding the back of giraffes for laughs is alright for a while."
