Some more red for the dessert

Being a kid during the Cold War, in a country close to the Soviet Union, means that I've had my fair share of the Red Army Choir conserts (on television). I remember the choir as a group of grave men singing "Volga, Volga" without flicker a muscle. That's why I found this clip from a consert they made around 1993 with a finnish rockband interesting. Has nothing to do with gardening, but perhaps you could wonder what fertiliser the boys have used for their hair.
