I went last night and they introduced him but i can't remember his name, although he was English.
Thought the concert was pretty good, the screen and light show was probably the best i had seen, miles better than the over-rated U2 one. Negatives were the half versions played of many songs and the Brian May guitar solo which was way too long or probably not needed at all considering May was front and centre nearly all night. Not sure a band with that back catalogue needs to play covers too. Adam Lambert is excellent. Freddie gets a good run and those sections were good. Poor old John Deacon doesn't rate a mention.
