Everybody has the right to love that music. And I like it, that so many new people still get into it.
For me the story of "Queen" ended in 1991. But I consider everything else as a welcome encore. I don't have to like everything, but I also didn't like everything before.
From a musicians standpoint it's absolutely normal, that May and Taylor want to play as long as they can.
So whatever happened since, the Musical, QPR, QAL, The movie....it all helped to keep the music and the memory alive.
I don't "get" the bashing of "whoever sings the songs", cause it all led to the fact, that Freddie Mercury - although dead for nearly three decades - has more media presence nowadays than he ever had in his lifetime. I can assure you, I was there....
And the band still plays the biggest venues. When you compare all that to other huge acts from the 70s and 80s, who play nowadays in shopping malls, smallest clubs or are nearly forgotten, "Queen" must have done something right.
I think I already wrote it somewhere on this board. "Queen" was never only about Freddie or the bandmembers. "Queen" was about the songs and those always attracted a huge audience. Even when no member of "Queen" was on stage at all. The audience was and still is "the star". And as long as the audience is there, everything is fine.
Enjoy the music, that's what it's all about.
