Passage: The music was composed by Balys Dvarionas and Jonas Švedas, and the original lyrics authored by Antanas Venclova. After Joseph Stalin's death, Vacys Reimeris changed the second stanza of the lyrics to remove mention of Stalin. The second stanza lyrics were changed to state that Lenin had lit the path to freedom, helped by the Russian people, led by the party (Reimeris changed the word "Stalin" to "party") and exhorted the Lithuanian people to work with peoples of the other Soviet Republics. This Soviet era anthem was confirmed in Article 169 of the 1978 Constitution of the Lithuanian SSR (this is the version presented below).

Question: Who composed the soviet era anthem?
