As Stevie Young, nephew of Angus and Malcolm, joined the band in Vancouver ahead of recording sessions for their next album, musicians and industry heads including Jason Hook from Five Finger Death Punch and Wendy Dio - Ronnie James' widow and manager - spoke out on the band's future.

Dio says they should continue. She says: "Absolutely. They are a legend." But Kirk Windstein of Crowbar and formerly of Down disagrees. He says: "No. Not this far in. I know he had a few problems with drinking years ago and his nephew or someone had to fill in for a few tours while he got sober. It's just my opinion but my God, it's AC/DC, what else do they have to prove?"
