4. Bob Dylan and Johnny Cash at Cardiff, 1966 - God Knows What
Bob Dylan fans have spend the last 40 years debating which drugs he took on his infamous 1966 European tour with the Hawks. Some are convinced it was heroin, while others say it was merely a hearty dose of amphetamines mixed with booze and very little sleep. Dylan is reluctant to admit he was on anything, though in 1969, he did discuss the matter with Rolling Stone. "I was on the road for almost five years," he said. "It wore me down. I was on drugs, a lot of things. A lot of things just to keep going, you know? And I don't want to live that way anymore." Filmmaker D.A. Pennebaker shot Dylan on the 1966 tour, and in many of the scenes, it's quite clear he's on something.
When the tour hit Cardiff, Wales on May 11th, 1966, he met up with Johnny Cash backstage. The country legend was at the height of his well-documented pill addiction. He was swallowing Dexedrine and Equanil like candy, and it nearly killed him. Pennebaker shot Dylan and Cash playing some Hank Williams classics, and it seems like both of them are on the verge of collapse.
