After five failed attempts to enroll in Moscow's State College of Circus and Variety Arts, Amarantov was successful on his sixth application, supported by well-known clown-mime Leonid Yengibarov, who was a member of the selection committee.

[1] In 1962 Boris graduated from state college with the performance Ke-la-la (backing track Chella llà), which was staged by Sergei Kashtelyan.

The spot was based on the combination and contrast of two different songs: Top, Тop, Stomping the Вaby by Tamara Miansarova and a composition called I Want You to Be My Baby, performed by American singer Lillian Briggs.

[1] As a result of intrigue from senior officials of the Russian Soviet Federative Socialist Republic (RSFSR) Ministry of Culture,[1] the theatre was closed several times.

[citation needed] The circumstances of Amarantov's death remain unknown as official medical examination was kept hidden from the public either by his relatives or doctors.
