Kai Warner - Bulldozer (1979)

German bandleader Kai Warner (AKA Werner Last) plays his version of the song Bulldozer, which was the theme from the Bud Spencer movie Lo chiamavano Bulldozer and originally recorded by the Italian pop duo Oliver Onions. Warner's version is from the album Kai Warner bittet zum Tanz 2, which was part of a series of strict tempo dance albums that he recorded for Philips.
Edit: a slight error in the video, as the recording is from 1979, not '78.
