Musicians announce boycott
Thirty-four of the world's leading musicians yesterday protested against the invasion of Czechoslovakia.
The protest read: "The occupation of the Republic by the five nations of the Warsaw Pact is a violent contradiction of the 
humanitarian ideals we have as artists.
"Until all foreign soldiers have withdrawn from Czechoslovakian territory and the legal government of the C.S.S.R. is free 
to govern again, it is impossible for us to keep artistic relations with these five nations and Czechoslovakia."
