DAMN! You found that video quick!
It was on an old 8-track copy of "The Captain and Me" by The Doobie Brothers that someone had recorded over. There was a lot of dead air on the drive between Fayetteville and Little Rock Arkansas up into the mid 90s, so I assumed that a college student going from UofA down to Little Rock had recorded Bo James' afternoon show for his drive. I derived the date of recording by the tracks in the program.
It's all here, including the campy locally produced 70s commercials, some of which feature "Struttin'" by Billy Preston... all while exclaiming that the local carpet dealer only stocks items with "No dogs... no flaws, man!" Take notice that Bo deliberately states the time of "4:20" when going into a break. A coincidence? Ah... the golden days of FM!
I bought the 8-track nearly 15 years ago, and dubbed it onto MiniDisc immediately. The recording is equalized because the raw recording was pretty weak. I used to own a 1977 El Camino, and a CD copy of this was always handy to give my passengers the full 70s treatment!
