Each member of The Monkees had a stand-in during filming of their television series. Michael Nesmith's original stand-in was John London, but in 1967 London joined the Lewis & Clarke Expedition, a country rock group that also included Michael Martin Murphey, an old friend of Michael's and the songwriter responsible for "What Am I Doing Hangin' 'Round?" (and "Oklahoma Backroom Dancer").
Nesmith's brother-in-law, Bruce Barbour, replaced John London as Mike's stand-in on The Monkees during the second season and while filming the movie Head (as seen in the photo below). Barbour went on to become a respected Hollywood stunt man.
