Via The Quietus:
1) On the 1975 Autobahn tour, Kraftwerk were supported by a folk singer from Somerset called AJ Webber. “They weren’t the easiest [people] to talk to, probably due to the language barrier,” she writes, via email. “But they were polite and reasonably welcoming. They drew a certain 'following’! We warmed to each other as the tour went on.” She also supported Frank Zappa (“I loved Frank!”) supporting bigger bands, as it was just her and her acoustic guitar, so no fancy changeovers were needed in the interval. She also seems to remember that one of them said they had ancestry that went back to Beethoven, but can’t remember the details.
