The Maltese vocalist was invited to audition for Angus Young and co in 1980, following the death of Bon Scott. But he declined because Swiss outfit Krokus were enjoying their own success at the time.

AC/DC this month reported that Johnson was ordered to stop touring immediately or risk a total loss of hearing. They cancelled a run of shows on their Rock Or Bust world tour, but said they'd be rescheduled, probably with another singer in place.

Storace tells Blastechno: "Obviously there's my loyalty to Krokus, but the guys would understand if the offer came. I would certainly take it up this time and go for an audition.

"Then it's up to Angus to decide. For me, AC/DC is Angus Young - no offence to Brian Johnson. I think Brian did a magnificent job with his unique kind of voice. But losing your hearing is not a nice thing."

Both bands are signed to the Sony label, making it possible that negotiations are already underway. Storace says: "I actually didn't even have to call Sony. They were already on the ball. This thing is not an easy thing to decide.
