It is maybe my favourite from the Chicago DVD. No effects, no nothing, except the four of them. Edge isn't playing guitar, neither. And sounds really great. I've said they should do something like this for ages (since Pop, or even before). Would they have the guts to do a whole tour just like this? all songs arranged for piano, and maybe bono on guitar? No effects, no big blinding show, just them. What do you think?
