It's taken some time for the dust to settle, but now it looks like we know who will be behind the drum kit for AC/DC's upcoming world tour -- and it won't be Phil Rudd, whose next date with a New Zealand judge has been set for April 21.

Following a recent report regarding a delay in Rudd's defense against charges of possession of methamphetamine, possession of cannabis and threatening to kill, Yahoo! adds that the proceedings will commence as a "judge-alone trial" -- which is pretty much what it sounds like, and customary for certain types of offenses under New Zealand law.

Rudd, who was forced to find a new attorney after his previous lawyer resigned, has made it clear that he intends to return to the AC/DC lineup once his legal troubles are behind him, but it looks like he may not have a choice in the matter.

As was heavily rumored, drummer Chris Slade -- who served with the band during part of Rudd's 1983-94 absence -- returned for their performance at the Grammys last night and he'll reportedly remain on board for the tour behind their latest album, 'Rock or Bust.'
