Review of Adventures in Rainbow Country

I caught one episode and watched it with interest since as a Canadian it is rare to find old Canadian shows since they rarely make it to vhs tape and DVD. (Still trying to find the first 3 or 4 seasons of the Beachcomers.) This show is supposed to be set in Canada, but aside from Lois Maxwell who does have a real Canadian accent here, my jaw dropped as the young blond actor who played Billy came on the screen. He spoke with such a cockney British accent that I thought I was listening to Eliza Doolitle from 'My Fair Lady'. And then next comes the actor who played Roger, and I swear if you close your eyes you would think this guy sounds more like John Lennon speaking in an interview than John Lennon himself sounded! Just wow. Canadians don't sound like that. What on earth were the Canadian casting directors thinking back then?
