There isn't an interview from FReddie in 1991, He also didn't an interview in 1990. I think his last interview was the 'Queen for an Hour' show on the radio
According to Peter Freestone was the last interview in August 1991 and October 1991 in Montreux.
And even had an interview in November 1991 with the Freestone which was several hours before death.
But I know of a conversation in July 1987 as Freddie talks about Monseratt Caballe.
"And even had an interview in November 1991 with the Freestone which was several hours before death."
