In 2012, the band were heading south after a gig in Glasgow when their tour bus careened 30ft off the road near Bath. Nine people were injured and Baizley's arm was so badly crushed that doctors considered amputation.

But a hospital call from Hetfield, who was in the bus crash which claimed the life of Metallica bassist Cliff Burton in 1986, gave Baizley hope that he'd make a full recovery.

Baizley tells Rolling Stone: "It was late at night in the trauma ward and most of the people I was in the room with were elderly, and they'd gone to bed early. The nurse was an older lady, and she said, 'Somebody just called you - a Jim Hatfield or John Hartfield, something like that. I told him I wasn't sure if you were awake or taking calls.' I said, 'I don't know anybody by either of those names, but I don't care if they're trying to sell me a dishwasher or life insurance - bring me the number, because I need somebody to talk to.'
