In 1981 Gerhard and his friend Mikael played in a punk band called Obstipation. After that he went into heavy metal and then big band student music and jazz. Then he had a long pause from music. Examples of songs written by Gerhard in his youth are available here. Obstipation started again in 2016 and together with a third band member (Gareth) they play "unplugged" music and rehearse on a regular basis. They also perform mostly at restaurants and events. Obstipation plays covers of popular songs from the 70's, 80's and 90's, but one tune from the early days called "sport" is on the setlist (see facebook for examples).
