Queen has released a video - shot in 1986 - featuring interviews with all four band members.

The interviews came as promos for the release of the album A Kind of Magic, which had a tie-in with the release of the film Highlander.

"We did all the music for the film first and they dubbed it on," says bassist John Deacon.

"When it came to doing the album, we re-arranged a lot of the tracks and made them longer and wrote more lyrics, tried to make them into fully-fledged songs.

So they stand up in their own right, without necessarily having to be with the film."

Freddie Mercury, who died five years after the interview, explained how he reworked the track "Magic."

"We all have our own ideas of how a song should be. In the case of Roger Taylor's track, 'Magic,' he did it in a totally different way which was quite good. But I just felt there was another commercial streak."

"I realised he was going away to LA for a week so I got hold of it and I change it round completely. When he came back I said, 'What do you think?' And he said, 'Oh, I like it.'"

"It was a completely different song but sometimes you can see something different in other people's songs. They do that to mine as well, we all help each other."
