Brats was an important band that led to creation of Mercyful Fate, formed in 1977 as a punk band (Hank Shermann was in the original line-up).They had three songs featured on the semi-famous Pære Punk compilation LP : "Dreams", "I do what I wanna do", "Magazine" (which later appeared on the 1980 album as "Zombie People" with new and improved lyrics) The group more or less broke up in 1979, but Hank reformed Brats later that year in a heavier outfit, featuring Yenz, Monroe, and a bit later Michael Denner.After the release of the first album in 1980, Denner left (replaced by Carsten Van der Volsing), and King Diamond  (from Black Rose) was recruited as new vocalist.But the LP failed commercially and in 1981 the record company CBS told the band that their next LP had to be more commercial rock and with Danish lyrics. Shermann and Diamond refused, leading to the end of Brats relationship with CBS, while Yenz and Monroe left and continued for a little while with The New Brats. The remaining members Hank Shermann, King Diamond and Carsten Van Der Volsing recorded a new demo in March, changing the bandname into Mercyful Fate since the music was much heavier than anything Brats had ever done.One month later King and Shermann helped out Michael Denner on his new project Danger Zone . As a result, Danger Zone and Mercyful Fate fused in a brand new line-up.The "real" Mercyful Fate.was
