A US radio station has reported that not only are AC/DC about to announce a world tour, but that frontman Brian Johnson is back in the line-up.

Kansas rock station V100 say their "sources" told them the rock icons will announce the tour next week.

The rumours come just months after US band Terrorizer claimed they ran into Johnson at an airport, saying, "We asked him about the rumors of him being on the new AC/DC album and he said 'yes' and that he is 'sick of denying it.'"

Johnson has been missing from the AC/DC line-up over the past few years, with Guns 'N Roses frontman Axl Rose stepping in his place, due to severe hearing problems.

However V100 reported today, "Brian has been working special in-ears made for his performances so that he can continue to perform without causing any more damage to his hearing than he already has".

The Music has contacted AC/DC's label for comment.
