So far it looks like whoever is supporting the main gig will also be playing the aftershow with a (possible) appearance from Prince.

There also seems to be a fair bit of info floating around (some most likely just rumours) as to who has been invited to play: Groupo Fantasma, Mika, Beverly Knight, Chaka...

How about a thread detailing which support acts are confirmed for which nights? Might make planning the aftershows a little less frustrating...
