Many, if not all, of the actors who worked on Ranger Bill also played in other programs. The following is what I found from the Geocities page below:
"The series was narrated by Miron Canaday who played an old Bill Collins remembering the adventures of his youth. Some of the other voices were Jon Gauger as young Bill, Gisli Bjorgvinsson as young Bill, Randy Paradise as Poetry, Kim Rasmussen as Dragonfly, Flo Schmid as Little Jim and Mrs. Collins, Rex Brenner as Old Man Paddler, Larry Moran as Barry Boyland, and Larry Shackley as Big Jim. Click on the picture of Larry Shackley (on the Geocities page) to listen to a two minute clip from "The Lost Campers."
You can order books, tapes, videos and CDs from Beloved Books and from Education for the Soul links. The gentleman with the Geocities site is a fan of the stories and has assembled an impressive list of information about the gang.
