I grew up in the 50's and like most kids my age was a big fan of the Mickey Mouse Club.In it's first season one of the segments was Spin & Marty.It was a serialized story about two boys at a western summer camp - who even got to ride horses thus becoming the envy of every boy watching. Spin (the All-American boy) was played by Tim Considine,and Marty (the snobby rich kid) by David Stollery.It became a HUGE hit & the sensation of that first season.Both boys appear in Her Twelve Men,and met there.Tim originally tried out for the part of Marty,but was offered Spin instead.Disney still needed a Marty and Tim told them he had recently worked with a boy who would be just right for the role,David Stollery from Her Twelve men!So this film was somewhat responsible for the ideal casting of that well-loved Disney serial.This information was related by Tim & David in the interview feature of the Disney Treasures DVD Box Set that came out a couple years ago.
