After the October Revolution, Politprosvet commissioned him to write propaganda songs for the new government. From 1919 to 1923, Pavel Gorin collaborated with Dmitry and Samuel Pokrass and authored a few military songs, including "Red Army Is The Strongest" («Красная Армия всех сильней»).
In 1940, Pavel Gorin went to Lvov, which was occupied by the Red Army, to create a Russian repertoire for a newly established Henryk Wars Theatrical Jazz. This Polish ensemble recorded a couple of songs translated by Gorin, including waltz Tylko we Lwowie («Прощальная песенка львовского джаза») and foxtrot Nic o tobie nie wiem («Ничего не знаю»). After returning from the battlefields of the Second World War, Pavel Gorin was writing interludes for a famous comic duo Tarapunka & Shtepsel.
