Everything seems to be back on track for AC/DC. The same can**t be said, though, for the group's longtime drummer Phil Rudd. He was arrested in **vember for trying to hire a hitman and threatening to kill. The hitman charge was dropped, but he could still go to prison for the threatening to kill charge. Either way, Angus Young and Cliff Williams said in a recent interview that the band has to move forward without him. Young recalled Rudd's erratic Behavior during the sessions for their 15th international studio effort, "Rock or Bust," Blabbermouth reports. "His Behavior has Been a bit strange," he said. "'Cause when we were doing the album, one minute he was coming, the next minute he wasn't coming. So it took quite a while to get him to the studio. When he got there, he did a great job. [But] it's **t the Phil that we'd k**wn all over the years. He knew that we were promoting the album and doing stuff [like photo and video shoots], and again he said he'd be there and **, last minute, again, he didn't show." Rudd missed his court date earlier this month. A full review of the case will occur Feb. 10.
