I`ve been to Queen concert and it was great! The stadium was full and the people sang Queen songs all the way, were very enthusiastic and responsive. I think Brian and Roger were pleasantly surprised by the fact that everybody knew Queen songs lyrics even those of not so popular songs like "39". Brian looks well, slender with long hair, seems not to have changed much. Roger sang his wonderful song I`m In Love With My Car. The stadium exploded. Paul Rodgers sang very well, the only problem is that he`s not that well known. So when he sang songs from his career, actually three, he got less applause than for Queen masterpieces, and he said: Thank you so much! kind of ironically. But the songs from Cosmos Rocks are very good (C-lebrity) and though not promoted much yet they were received by the audience very enthusiastically.
I would recommend those who like Queen to attend the concert by all means and first of all enjoy the old Queen songs, and certainly to buy the new album Cosmos Rocks. It`s less Queen, it`s modern and more rock.
