June 29, 1980, Namur, Belgium: four months after Bon Scott’s death, a terrified Geordie sang his first AC/DC show weeks before Back in Black came out. Fans later carved the spot a monument.

Their debut was weeks from release when Andrew Wood died at 24. From the grief came Temple of the Dog, Pearl Jam, and Seattle’s great what-if – the band that ended before it began.

George Young misremembered Bon as a piper – he’d been the pipe band’s drummer. So Bon bought bagpipes that afternoon for $479 and learned them mid-session. The true story of rock’s greatest bluff.

Iommi doubted him, critics savaged him, and the voice they all dismissed became one of the most recognisable sounds in music. Why ‘he can’t sing’ was the wrongest verdict in rock.

August 22, 1969: two days after their last recording session, four bearded men, a sheepdog and two donkeys gathered at Tittenhurst Park – and nobody said the word ‘last’.
