Estonian composer, Veljo Tormis, born 1930 and deceased last month, composed a cantata: Lenin's Words [Lenini sõnad] in 1972, at the occasion of the 50th birthday of the establishment of the USSR, in three movements:
1. What is Soviet Power?
2. The Complete Equality of Peoples
3. The Tomorrow of World History
for soprano, female choir, male choir and mixed choir, on texts by Lenin.
When I first met him, in August 1993, he told me that he had chosen words from Lenin's famous 'Testament' that were not acceptable to the Soviet authorities at the time - especially as they acknowledged minority rights. :D
I see the story is confirmed by Mimi S. Daitz in her monography on Tormis:
