The Bremen Town Musicians (1969)

The traveling musician, his animal friends, and the princess The Bremen Town Musicians (, Bremenskiye muzykanty) is a 1969 Soviet musical cartoon made at Soyuzmultfilm, directed by Inessa Kovalevskaya and written by Yuri Entin and Vasily Livanov, with music by Gennady Gladkov. It is loosely based on the Brothers Grimm fairy tale, Town Musicians of Bremen. The film became a cult hit in the Soviet Union because of its memorable musical soundtrack, which contains influences from Western rock 'n' roll music. Two sequels were made, including On the Trail of the Bremen Town Musicians (1973) and The New Bremen Musicians (2000).
