On this day, 14 March 1973, heavy rock band Black Sabbath played Cardiff’s Capitol Theatre with support provided by Badger and Necramandus..
The band were promoting their fourth studio album Vol 4, released in September 1972. It was the first album by Black Sabbath not produced by Rodger Bain; guitarist Tony Iommi assumed production duties. Patrick Meehan, the band's then-manager, was listed as co-producer, though his actual involvement in the album's production was minimal.
In his autobiography I Am Ozzy, Osbourne speaks at length about the sessions: "In spite of all the arsing around, musically those few weeks in Bel Air were the strongest we'd ever been." But he admits, "Eventually we started to wonder where the fuck all the coke was coming from ... that coke was the whitest, purest, strongest stuff you could ever imagine. One sniff, and you were king of the universe." During a show in support of Vol. 4 at the Hollywood Bowl, the cocaine abuse caught up to Iommi. "Tony had been doing coke literally for days. We all had, but Tony had gone over the edge. He walked off the stage and collapsed," said Osbourne. During soundcheck earlier that same day, a crazed Christian man attempted to storm the stage and stab Iommi with a dagger, but he was tackled by members of the band's crew. According to Butler, "we wanted to take a break" at that point.
