I've been going through old radio trade magazines and there are a lot of listings of Queen interviews that aren't readily available, but what I found particularly interesting were 3 consecutive weeks of interviews during the US Jazz Tour:
WYSP Philadelphia December 8, 1978
QFM97 Buffalo December 15, 1978
KZOK Seattle December 22, 1978
It didn't specify which members were interviewed. Does anyone have these? I don't think I've heard a radio interview from the Jazz tour. One magazine also said that a TV station from Argentina was recording interviews with fans outside of the New Orleans show, so I take it they could've conducted some interviews as well...
