in Norway and Denmark in 1967, performing some of the songs from the television program. His performance in Oslo on September 10 was recorded on video tape and aired locally that autumn, then released on DVD some 40 years later. He performed as a prominent international guest at the Studenterforeningen (student association) in Copenhagen, which was televised, and he commented on stage that he might be America's "revenge for Victor Borge". He performed original songs in a Dodge automobile industrial film distributed primarily to automobile dealers and shown at promotional events in 1967, set in a fictional American wild west town and titled The Dodge Rebellion Theatre presents Ballads For '67.
