Shortly after, Jon recorded the album "Keep the Dogs Away" in 1976–77 through his own company God Of Thunder Productions. The album was licensed to RCA and released in early 1978. Jon appeared on the cover artwork as "Thor The Rock Warrior", holding back four dobermans. In February 1984 Thor performed at the Marquee in London, England, to great reaction from the audience which included Jimmy Page of Led Zeppelin. The review in "Kerrang" magazine proclaimed "He Came, He Thor, He Conquered". The reception of that show launched Thor's career to a new level. He then licensed recordings to Albion Records. Albion released songs such as "Thunder On the Tundra" and "Let the Blood Run Red" which went to #1 on the UK Rock Charts. Thor toured throughout the UK performing at such concerts as the Great Yarmouth Festival and released albums such as "Only the Strong" (1986) and "Recruits - Wild in the Streets" (1986).
