Dannemann was first introduced to Jimi Hendrix on 12 January 1969, in Düsseldorf, after being invited to a Jimi Hendrix concert there. She spent that night with him and part of the next day too, when she accompanied him to his next concert in Cologne; after that, she returned to Düsseldorf. He spent the last night of the tour with famous model and "scenester" Uschi Obermaier, with whom he was filmed kissing and petting outside the Kempinski Hotel the next morning. He wrote to Dannemann on 25 March 1969, inviting her to visit him in New York City. Dannemann claims she next saw Hendrix when she travelled to London on 25 April 1969 in the hope of meeting him again, where she bumped into him at the Speakeasy Club. She says they spent some time together over the next nine days, but she only spent one night with him.
