Rolf received the name "Rock 'N' Rolf" after the following story. One day the band was practising in the cellar of Matthias Kaufmann's house. Matthias's little brother Markus was trying to follow all the terms he was hearing, such as "Rock 'N' Roll", "Heavy Metal" and new stage names which the band was talking about. One day, he was listening to his brother and Hasche talking about Rock 'N' Roll. The doorbell rang and, when Markus opened the door and saw Rolf there, he shouted confused, "Rock 'N' Rolf is here!" - the name stuck.
