Internet meme.
In 2009, a 1976 video of singer Eduard Khil singing Ostrovsky's vocalise "I am very glad, because I’m finally going home" (Я очень рад, ведь я, наконец, возвращаюсь домой) was uploaded to YouTube and quickly became an Internet meme known as "Trololololololololololo." The song itself was written by Ostrovsky, and was also performed by Valery Obodzinsky and by Muslim Magomayev on Little Blue Light.
Ostrovsky's son, Mikhail, is quoted as saying:
Hootenanny Singers.
Ostrovsky is the author of dozens of popular songs in the post-Soviet countries.
For example he is author of music for the song "Let there always be sunshine", which was "taken" under the name of 'Gabriel' into repertoire of the swedish band 'Hootenanny Singer' without specifying the author.
