"Yes, we're this happy"

One of the year's most improbable tips (let's draw a veil over the memory of Polyphonic Spree shall we?) is I'm From Barcelona, a 20-odd strong collective from Sweden with a nice line in songs about chicken pox.

From their first song about a 'you and me house' tree house in which their Angus Young-a-like singer sprinkles streamers over the crowd (with a handful just for us down in the photo pit. Touched by celebrity, that's us!) there's all sorts of excitements going on. A bubble machine whirrs around the stage and girls clutch twigs left over from British Sea Power's set last night. It's waaaay less scary than the Spree and their 'rhymes with slaughter' leader but none the less full of joy and fun. We particularly enjoy the bearded man dressed up as a Smurf and bouncing like he's on a trampoline.

Angus and one of the tree girls get down in the pit and get people in the crowd blowing into kazoos and singing along like they were born into a musical collective. It's brilliant and ludicrously happy. We are forming a musical collective THE MINUTE we get back to London. Who's with us?
