Koppel interviews Zappa, Donny Osmond, and Kandy Stroud regarding -- what else? -- the Porn Wars. Uploaded by koolstrike.
Kudos in particular to Nightline for pointing out that Love for Sale was once banned from radio and Louie, Louie was investigated by the FBI for having allegedly obscene lyrics. The pro-censorship crowd argues, as always, "Well yes that was silly, but this time is completely different!" Much like people advocating video game censorship today.
Zappa also meets a potentially-unexpected ally in Donny Osmond, who is opposed to the music rating system on the simple grounds that R-rated movies make more money than G-rated ones and music ratings would be a threat to the sales of Osmond's squeaky-clean music.
