I`m just guessing this is from 1980. It could be from 81 or 82, but somewhere in that time-slot. The time-slot is: “When we were trying to play cool, new 80s music but we still had to play with some bearded dude from the 70s”
I´m also just guessing this is from Berlin because it has the Berlin area code listed on the back. “Kleiner Pilot” is not Punk, not Power Pop, not New Wave but it`s trying very hard.
