But he played "Trans-Europe Express" which is not co-composed by him!
The October issue of the German magazine "Keys" features an interview with Karl Bartos, in which he states that he did contribute to the compositions on the "Trans Europe Express" album, but hasn't received credits for his work on the album sleeve. Although his wording is not absolutely clear, he seems to imply that he generally did most of the composition work for Kraftwerk. Quote: "So it is if you work in a team. 'Yesterday' was also credited to Lennon/McCartney, although it is a McCartney song". And when he was asked if there is a conflict with the remaining Kraftwerk members, he replied "If the metaphor 'due to artistic differences' is used, the actual reason is always money - in every band in the world".
