Mojmir "Mojzes" Sepe (11 July 1930 – 24 December 2020) was a Slovenian composer, conductor, arranger and trumpeter.

In 1950, he started his professional music career as a promising trumpet player at Radio Ljubljana Dance Orchestra.

His trumpet career ended after an altercation at Opatija Festival '65 when four guys knocked out a couple of his front teeth as he defended her from having her purse stolen.

Among them were Frane Milčinski Ježek, Gregor Strniša, Branko Šomen, Miroslav Košuta, and Ivan Minatti.

However, Sepe and Budau never officially complained or filed a lawsuit against Eres Tú composer Juan Carlos Calderón, and therefore nothing further happened.
