We been down the Motorway and the Highway. Today "Wir fahr'n, fahr'n, fahr'n, auf der Autobahn" for the latest 'One For The Road' track.
Issued today to mark the 50th anniversary of Kraftwerk's iconic 'Autobahn' album, with releases on three different formats including a Picture disc. 

Funnily I always thought they sang 'Fun, Fun, Fun on the Autobahn'...

Band member Wolfgang Flür explains: 

No! Someone else told me that they [the misinterpreters] thought the way we speak in German "Fahren", which means driving, sounds like the English word "fun". "Fahren fahren fahren", "fun fun fun". That is wrong. But it works. Driving is fun. We had no speed limit on the autobahn, we could race through the highways, through the Alps, so yes, fahren fahren fahren, fun fun fun.

Even the video uses 'Fun, Fun, Fun' > beep, beep 

The original album version of the song lasts 22 minutes, but the track was edited down to 3 minutes for its single version, b/w ‘Morning Walk’ (Morganspariezgang), released Feb 1975.
