"Witchdoc" was a temporary M.C. 'nom-de-plume' for Jorun between the late 1980's and up until 1998. Jorun dropped the "Witchdoc" from his name in 1998 once discovered there was another artist releasing records with the name "Witchdoctor". To avoid confusion, the name was no longer used or attached to future releases.
The name "Witchdoc" is only attached to past releases prior to 1998 where relevant / noted in credits.
