I found this video containing radio jingles for pirate radio stations in the Netherlands.
I only recognise a few tracks:
-Radio Centraal and Delta Radio both use the Pepper Tanner package “The Spirit of…” originally created for KSD (AM).
-I’m assuming Radio Roulette uses an Alfasound Tapetrix package originally created for BBC Radio Northampton.
