Did you ever run into Uncle George Sivers who had a dog and pony show that criss crossed the states in the 1960s? Probably was before and after that as well.

Any one remember Dell O'Dell - She had a short lived TV Program and a Magic Shop in Hollywood, Calif. in the mid 50's

I may have "run into him". In '85 season, I was managing Tim Deremer's Ape show (For you townies, that's a girl to gorilla illusion show.) We showed a bunch of fairs, down south, with Degeller Amusements, and there was an old timer with a dog and pony show at a few of the same spots. He toured in a remodeled old school bus. He, the dogs, and the pony, and the show props all lived in the bus. He seemed like a nice old timer, but, like many old carnies, I never asked his name.
