They haven't but I think if they did Mofo they would probably make a diferent version to it, they changed a lof of the songs or so it seems by the reports. So if they did Mofo it would probably be something more organic so that would be kind of.... awesome!!!!!!!
I think that the next tour should bring back Mofo.
Maybe they could do 1-2 songs from each album, like a retroperspective on their career, and not care about playing loads of songs from their new album.
