Rehearsals begin in Turin
Reports have come in from U2Place.com's Twitter account that U2 have arrived in Italy and begun rehearsals in Turin ahead of the second leg of the Innocence + Experience Tour.
A number of songs were rehearsed on Monday. They included New Year's Day (not yet performed this tour), Every Breaking Wave, October, and - perhaps the most significant news - Bullet The Blue Sky with a Zooropa outro. Tweets about rehearsals are here and here.
Zooropa has only been performed in Europe three times, and all of those (somewhat truncated) performances were over 22 years ago in August 1993 at shows in the United Kingdom. It has never been played in continental Europe. After those three August 1993 performances, Zooropa was played at 28 shows in South and North America in 2011. You can view the full list of its performances here.
