I don't think you're completely right here, I was at all the debuts songs next summer, of course nobody could sing them the first times, because nobody knew them, but Glastonbury was danced by almost everybody, Mercy was an old friend of most fans, so the GA was full of people singing the verses, North Star and Every Breaking Wave were acustic and nobody was to jump at those, we weren't waiting for them to finish, we were listening, which is quite important at a concert too, by the middle of the leg many people new the lyrics and sang along them, but of course, acustic songs means no jumping, North Star was sung by the whole stadium in Munich, finishing the song with the chorus being repeated by the crowd several times, the way we usually have ISHFWILF, I've only listened to BFFTS once, people aplauded warmly to it.
But it is not only that, if you weren't there, you can't imagine the flow of emotion that there was among the fans when the surprise part of the show started, it is the best present the band could have done to their fans, it was something indiscribable and we felt being part of something very especial and the band felt it too.
What happened to the occasional fan? nothing different from when they play The Unforgettable Fire or Ultraviolet, we may think that they are universally known, but they aren't, I was asked for their titles more than once.
