Just picked up something interesting when I was reviewing videos of the Sydney concert..
When he lets fans pick 2 songs he goes "I need to remind you guys in case you guys forget me..We need to revise otherwise we forget, so lets sing songs from long long time ago..lets get the audience to pick the songs..dosn't this feel more sincere ?"
So he says sing songs from long time ago, THEN he says let the audience pick songs. Is he subconsciously admitting that older songs will be picked/are preferred, because he knows that if audience picks songs, they will pick the older songs..
Hopefully its true that he is going back to old style for the new album, at least a mix of old and new I would be happy.
