Whakakiia te rerenga e whai ake nei: I purei a Rostropovich i The Proms i te po o te 21 o Akuhata 1968. I whakatangihia e ia me te Soviet State Symphony Orchestra <unk> koinei te whakaaturanga tuatahi a te roopu puoro i te Proms. I whakaatuhia e te hōtaka te konohete Cello a te kaitito Czech a Antonín Dvořák i roto i te B minor, a, i puta i te ra ano i whakahaeretia ai te Paati o Warsaw
I whakaekehia a Czechoslovakia hei whakamutu i te Spring Prague a Alexander Dubček. I muri i te whakaaturanga, i mua i te whakahe me nga whakaaturanga, i whakamoemiti te roopu puoro me te kaiwaiata takitahi e te hunga whakarongo o Proms. I tu a Rostropovich, a, ka mau ki te tohu a te kaihautū o te Dvořák hei tohu o te kotahitanga mo te whenua o te kaituhi me te taone o Prague.
