WATCH: AC/DC's Brian Johnson and Metallica's Lars Ulrich Remember The Times

Even the world's biggest rock stars get nostalgic sometimes. Such was the case when AC/DC singer Brian Johnson hosted Metallica drummer Lars Ulrich on his rock and roll TV show, Brian Johnson's A Life on the Road.

It was back in 1991 when AC/DC brought Metallica out on the Monsters of Rock tour, and a mutual admiration between the two bands was formed.
