Velkaverh, who was active above all in the music publishing business and was not a professional author, wrote the texts of around 600 songs, mostly for Slovenian composers but also for ensembles.

His name is tied closely to the blossoming of the Slovenska popevka festival of chanson and pop songs, which had its heyday in the 60s and 70s with contributions from professionally trained singers, composers and poets.

Velkaverh wrote the lyrics for one of the most popular Slovenian holiday songs, Silvestrski poljub (New Year's Eve Kiss), while the list of his biggest hits also includes Pridi, dala ti bom cvet (Come to me, I'll give you a flower), Zelene livade s teboj (The Green Meadows and You), Ljubi, ljubi, ljubi (Dearest, Dearest, Dearest) etc.

Velkaverh was born in 1943 in Georgetown, Guyana to a Slovenian sea captian and an English nurse. He also spent his childhood in New York, London and Belgrade before his family moved to Slovenia in 1956.
