From Njål A
The two shows in Oslo, were in clubs basements, Club 7 under what was then (from memory) an office building, where the main road was one level up, the entrance at lower street level, and the actual club down a flight of stairs (a lot of great artists played there),

Info from Wikipedia
Club 7 was a cultural club in Oslo, Norway, active from 1963 to 1985. It was regarded a centre for counterculture in Norway in the 1960s through the 1970s.
Club 7 was established in 1963 by Attila Horvath and Odd Schou.
The name "Club 7" is supposed to mean the club should be "more than sex" (the number 6 in Norwegian is pronounced like "sex").
The club had various locations over years, including Drammensveien 64, the Edderkoppen Theatre, the restaurant Kongen near Frognerkilen, and the Oslo Concert Hall. In the 1970s the club was located in Vika, in block D of Oslo Concert Hall.
The club closed in 1985 after bankruptcy.
