I suppose this one would have been more of a nostalga trip for the older generation in UK and Europe.
Radio Luxemburg 208MW was probably the most popular stations.It played the top chart pop songs very late at night. We all used to hide our little portable radio sets,pretend to be asleep,and then listen to the pops.lol

Anyway back to the puzzle answers.
A very small country= Luxemburg (Europe)
The town is Differdange.
Differ add aint (different)= somewhat odd.
Dange, add an "r"=danger.
Probably wouldnt expect any of the younger generation to get this one,or people outside of Europe.
cheers
