The original single version released before Autobahn.

On the single the two parts were reversed (the faster section was the first part, and the slower section was the second; also, the sound quality is a lot less polished in comparison to the finished versions on the Autobahn album. It is also slightly different musically and instrumentally - the faster section is played somewhat quicker and the slower part utilises electronic drums, whereas on Autobahn, this section used no percussion.
