Brian Johnson

AC/DC singer co-wrote "Never Gets Old" for Jackyl frontman's upcoming album.

He delivered “Back in Black” and “You Shook Me All Night Long” with fellow Newcastle native Sam Fender.

It commemorates the singer's first live performance with the band in 1980.

Singer says "it’s getting tabloidy" when repeatedly asked if band will return to action.

"I wish that I could have got to know him better," he says of AC/DC predecessor.

He's long since earned his spot at the mic, but at this point he was still the new guy.

The seeds for his arrival had been planted years earlier – and under most serendipitous circumstances.
