Unfortunately, I can't find any Hoyt Axton Show footage on YouTube, so we will have to make do with that crackling tune. There is also this awesome clip of Ringo Starr and a cast of many on a 1975 variety special:
Back to the 1981 pilot: Directed by Richard Crenna, this one features Axton as "a country singer who, after his wife dies, returns from life on the road to raise his 3 kids." Lee Goldberg's indispensable Unsold TV Pilots adds that the character's teenage daughter is dating a divorcee and his son is heading out on the road with a rock band. Yikes!
