In 1997, it was released on Zodia Shturec, Kiril Marichkov's debut solo album.

This version runs 3:00 and features an extra solo from Petur Gyuzelev that did not appear in the original.

A third version was released in 2008, but this time it was not by Shturcite, but by British indie pop band Ladytron.

A music video was filmed for the 1996 version, featuring Marichkov playing the song mixed with live and archival footage of Shturcite.
