Former Czech president and one-time dissident playwright Vaclav Havel was once said to have asked him, "Did you know I am president because of you?"

Here's the back story (hat-tip to the FT's Ed Crooks for reminding us of this story):

Sometime between 1967 and 1968, Havel visited the U.S., and scored a copy of a record by the Velvet Underground, the band founded by Reed and championed by Andy Warhol. (It's not clear which album Havel got — some accounts say it was their debut, others "White Light/White Heat.")

The band's liberating, experimental sound proved a sensation in the Czech artist community, as music writer Rob Jovanovic once explained:

Havel took it home, along with Frank Zappa's debut, and managed to smuggle it through Customs. Soon it was being copied and passed around the Prague underground, influencing the avant-garde set to play secretive gigs around the capital…"

One of the people who picked up the album was Milan "Mejla" Hlavsa, who played in a band called The Plastic People of the Universe.

Along with the Zappa and Captain Beefheart tunes, the PPU began incorporating VU songs into their sets.

In August 1968, the Soviet Union invaded Prague, and the repression that followed prevented the PPU from playing in public. Eventually, they were formally banned.

But they continued to play on underground circuits.

Finally, in 1976, its leaders were arrested, their music deemed anti-social. Lots of other artists were rounded up too, and their trial ended up giving birth on Jan. 1, 1977 to Charter 77, a dissident movement formed to protect human rights. Havel was the leader.

It took another 12 years, but eventually the Charter 77 movement brought about the fall of the Czech Communist regime.
