An incredible gig.

Pražský výběr - Prague selection - in 1991 played to celebrate departure of Warsaw Pact army from then Czechoslovakia. There were a Velvet Revolution in 1989 but we were still occupied until 1991. In the video, a helicopter with Soviet general leaving the venue is seen.  They literally drove the army out of our country.
(In fact, the general was in the audience and inflatable dummy soldier in the helicopter).
Frank Zappa joined Výběr on stage and played a guitar which he hasn't done for years before.
PS: Havel in the audience included.

Bye, goodbye
The fire's already lit
Bye, goodbye
The time's up
Bye, goodbye
Here's to a healthy fight
Bye, goodbye
To all the bullies

Adieu C.A.
