There's hope yet that frontman Brian Johnson will appear on the next AC/DC album.

According to Blabbermouth, US band Terrorizer ran into Johnson at an airport at the end of their recent European tour and asked if he will be appearing on the album, with Johnson reportedly answering "yes" and that he's "sick of denying it".

"We ran into Brian Johnson from AC/DC at the airport today after the flight home," said Terrorizer in a Facebook post, "And 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.' So that was a cool surprise ending to the tour."

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.

AC/DC's next album with be their first without guitarist Malcom Young, who passed away in 2017 following a lengthy battle with dementia.
