Brian and Freddie's sister Kash are often asked why Queen carries on without Freddie, but they both believe he wouldn't have wanted the band's music to just become "museum pieces".
He told the publication: "You know, I often have this conversation with Freddie's sister, Kash.
"She gets those questions as well; 'Why are they doing this without Freddie?' And she completely gets what we're doing. She says, 'This is what Freddie would have wanted. He would not want have wanted his songs or the band's songs to become museum pieces. He would have wanted them to live.' And that's what we're doing. We make the Queen legacy live. Absolutely."
Adam Lambert serves as frontman on their tours.
He continued: "The last tour we did was fantastic.
"Probably the biggest arena tour we've ever done, and the most exciting in terms of all the shows being sold out and the energy in those audiences. The thing is, people want live music. They need live music. And we're happy to go on supplying it as long as we can.
"As long as I'm alive, I'll be there!"
