Jan Akkerman at the Roskilde Festival 1975 in Denmark, photographed by Skiold.
"As you can see Jan had to get rid of cold-cramps (in the middle of Sylvia) in the cold Roskilde night. It was a great concert, the second I witnessed. The first was in the Tivoli Concerthall of Copenhagen, 1974. I still have the poster from that concert" - Skiold / Copenhagen
