They played Red Square, launched MTV Russia and got driven home from a gay club by the police. But the freedoms witnessed by Pet Shop Boys have been crushed. Singer Neil Tennant relives those heady days – and calls for a revolution

The journalist Andrey Sapozhnikov of Novaya Gazeta Europe, the independent Russian newspaper that now operates from Latvia in order to avoid censorship by Putin’s regime, recently asked Neil Tennant of the Pet Shop Boys: “You have been actively commenting on Russian politics since 2013 and the Pussy Riot case, and you are arguably one of the most engaged western artists in relation to the Russian context today. Why do you care so deeply about what is happening specifically in Russia?” Here is his reply, which the Guardian is publishing in English.

I have been interested in Russia since reading a book when I was a young boy about the 1917 revolutions. It fascinated me that the Russian empire was replaced by another empire, the Soviet Union, which unleashed a lot of energy but rapidly became a brutal dictatorship under Stalin, a 20th-century Ivan the Terrible. Since then I have read a lot about Soviet culture, particularly the work and struggles of Shostakovich and Prokofiev and other artists, writers, musicians. This interest fed into the lyrics I wrote. For instance My October Symphony, or indeed our first hit single, West End Girls: “In every city, in every nation / From Lake Geneva to the Finland Station.”
