When I just read the ( little funny ) suggestion "back to the future" I had the idea, that maybe TIME is a great Issue for the album, the tour, and maybe also the artwork.
There is a connection to the countdown clock to the 360 tour, to "what time is it in the world", etc. And now looking back to see forward, thats all has to do with time, getting older and wiser, being able to understand the view from a fathers postion, and so on.
So really, "back to the future" is maybe not far away...even Get On Your Boots said "Future needs a big kiss"....
So kiss the future, f*** the past :-
