"I loved Dan," says Johnson. "I wanted to sing like him. I was at a submarine base in Glasgow when they [Nazareth] were supporting Geordie. And I stopped and watched them first, and thought, 'What a band!'. And that's when I got the first feeling that Geordie were just getting left behind a little with this pop stuff."
The same night, McCafferty took Johnson out to the car park and played him a cassette of Nazaraeth's latest single, Broken Down Angel (released in April 1973). Johnson then ends the interview by playing the song, saying "Can I play this in the memory of Dan McCafferty – my good pal – and to all his family."
Johnson was speaking on BBC Radio 6's The First Time... with Matt Everett, where he detailed some of the most pivotal musical moments of his life. During the hour-long broadcast, he talks about the life-long impact of hearing Little Richard as a young boy, how he discovered his own singing talents in a Scout show, and about the experience of joining AC/DC in 1980 and recording Back In Black.
He also details some of his more recent history, from the hearing problems that obliged him to leave AC/DC in 2016, to the technological breakthroughs that allowed him to return, and the recent Taylor Hawkins show in London.
The show is punctuated by 14 tracks, which include songs by Bob Dylan and The Rolling Stones, as well as eight tracks featuring Johnson himself – one by Geordie, and seven from AC/DC. Complete list below.
In October, Johnson revealed the 10 songs that have soundtracked his life, while in conversation with BBC Radio 2's Ken Bruce show. Johnson's selection includes Black Sabbath's Paranoid and Led Zeppelin's Rock And Roll.
