From 1963 to 1965 he was the vocalist of the pioneering classic rock group Olympic, and from 1967 he subsequently performed as a member of the Semafor Musical Theatre, with Jiří Brabec.

During his career, he performed and recorded his own versions of rock-based standards, such as Lou Reed's "Walk On The Wild Side", and Frank Zappa's "Harder Than Your Husband".

With their historical connection in mind, in 2010 Bobek went to Nashville, Tennessee, United States, with producer Luboš Malina, where he made a CD of reworked Cash songs which he called "Víc Nehledám" ("Looking No More").

After a long serious illness, which almost cost him his voice years prior to his death, he partially returned to live concerts in May 2012, and released a new album called "Circles".

After attending high school, he went on to study architecture, among his classmates were Jan Kaplický, Eva Jiřičná and Petr Nárožný.
