(From Barcelona 2) "We got to hear 'Crazy' twice tonight: the band are shooting a video with Alex Courtez and tonight's performance is part of it."
They also want fans to contribute their own video clips (it says before the Barcelona shows, but I don't see any mention of a deadline so maybe you can still participate):
"WANT TO BE IN A U2 VIDEO?
GO CRAZY WITH YOUR CAMERA AHEAD OF THE FIRST SHOWS!
Going crazy about U2 opening their new tour in Barcelona? Getting ready for the first shows at Camp Nou?
What you going to be wearing? How long do you spend in front of the mirror? Any special requirements! What's your routine and who you meeting up with?
We're looking to feature some U2 fans in the video for 'I'll Go Crazy If I Don't Go Crazy Tonight' the band's next single. We want you to film yourself at home or with your friends preparing for the Barcelona shows - any format, blackberry, flip cam, cellphone, iPhone, whatever - and then we want you to upload no more than 5 minutes of footage over in the VIDEOS section, or if you can, in the Barcelona group over in the GROUPS section
GO CRAZY TONIGHT!
YOU JUST MIGHT END UP IN THE NEW VIDEO!"
No idea how this ties in with the previous mention of a presumably animated video (maybe they're making two):
"The talented Irish animation film-maker David O'Reilly has been commissioned to create a video for I'll Go Crazy If I Don't Go Crazy Tonight."
