This is a live, promotional video (with a live vocal track) of "Carry On Wayward Son" by Kansas, from the Leftoverture album. This is probably the official "music video" of the song.
It's too bad that no one else who recorded this decided to post it on any site. Actually, I will rephrase that. It's too bad no one else recorded this.
It is purely memory, I got the the title wrong as you can see, But I did record the audio of of COWS since VCR's came out around that time at $1,000. I do remember also they played a video that, I assume was made for the Great Allentown Fair which consisted of the band members and children that were used to emulate them with "Questions of my Childhood". So it was the concert and the video segments that were in that 2 hour show.
