The mystery of why U2 played ‘Vertigo’ twice in Chicago – see the current issue of Hot Press – has been resolved.

After a dry run, the second and third nights of the band’s United Center residency were filmed for their 2005 concert DVD, which will be in the shops for Christmas.

“The cameras went a bit haywire on the final night during ‘Vertigo’, so ever the perfectionist Bono instructed the lads to do it again during the encore,” explains a U2 source. “Going by all the jumping and leaping around, I don’t think the crowd minded too much!”

Directed by the same man who did their Elevation: Live From Boston and U2 Go Home: Live From Slane Castle films, Hamish Hamilton, the new sell-through will feature all or most of: ‘City Of Blinding Lights’, ‘Elevation’, ‘Cry/Electric Co’, ‘An Cat Dubh/Into The Heart’, ‘Beautiful Day’, ‘New Year’s Day’, ‘Miracle Drug’, ‘Sometimes You Can’t Make It On Your Own’, ‘Love And Peace’, ‘Sunday Bloody Sunday’, ‘Bullet The Blue Sky’, ‘Running To Standstill’, ‘Pride (In The Name Of Love)’, ‘Where The Streets Have No Name’, ‘One’, ‘Zoo Station’, ‘The Fly’, ‘Mysterious Ways’, ‘All Because Of You’, ‘Yahweh’, ‘Party Girl’, ‘40’, ‘Original Of The Species’ and ‘Vertigo’.
