The good folks at U2Songs have delivered the goods again from U2's rehearsals in Laval, Quebec. And the news is very interesting indeed. Read on if you want to spoil yourself silly.

Yesterday's rehearsal appears to have been brief. This one was not. U2Songs report the following songs rehearsed:

• Acrobat intro multiple times by Edge
• Acrobat, twice
• Who's Gonna Ride Your Wild Horses
• Acrobat
• Until the End of the World
• Acrobat

The band took a break and then ran through some more songs, though U2Songs is only 100% certain about the identity of the last one:

• The Fly, riffs only
• Desire
• The Showman (Little More Better)
• Vertigo, riffs only
• Lights of Home

The band took another break, though it is possible some rehearsing took place at this time at a volume low enough not to carry out of the arena. The band rehearsed Little Things with the volume off before last year's JT30 Tour, so they might be trying to keep something hidden—though given they're working on Acrobat loudly, it's hard to think of any song that could be an even bigger surprise to keep under wraps. The band then ran through five more songs:

• Cedarwood Road
• Song for Someone
• Who's Gonna Ride Your Wild Horses
• Acrobat
• Until the End of the World

That was it for the night. At this early stage in rehearsals, the band seem quite serious about Acrobat. Now, those of you who followed rehearsals in 2009 will remember what happened to Drowning Man, rehearsed extensively but never played, and Electrical Storm, performed just three times. But it is no surprise that after touring The Joshua Tree for a year, U2 are now turning to Achtung Baby. In interviews they have indicated as much is likely. Performing Acrobat would respond to a very vocal demand from the fanbase. Will U2 also respond to the clamour for something, anything from Pop? No indication as yet, but early days.

Fans have been debating how much of Songs of Innocence will stick around, given that this is the Experience + Innocence Tour. Today's rehearsals suggest that the album will retain a presence. Song for Someone and Cedarwood Road were both at the narrative heart of the 2015 shows. On the other hand, both of those songs spoke to the band's early "Innocence" years, not to the post-Joshua Tree "Experience".

Insofar as the new stuff from Songs of Experience goes, it is no shock to see Lights of Home being rehearsed, for it has already been performed once, on 17 November 2017, and it will be a Record Store Day single later this month. The Showman, however, is interesting—U2 have already performed nine songs from Experience live, but Showman is not one of them.

By the way, if Who's Gonna Ride Your Wild Horses gets dusted off, that will make this tour just the third on which it has been performed. It was played 63 times on the ZooTV Tour in 1992, of which the last four were acoustic. It was then dusted off for a few shows on the Vertigo Tour, initially for five electric performances and then eleven acoustic. The last of those performances, in Honolulu on 9 December 2006, was unplanned, in response to a fan request. If the song is performed, its first appearance this year would be its 80th performance overall.
