Rory signed the guestbook of "Kapuziner Klause" in Cologne, 18. Nov. 1987, where Rory and Rudi have been for lunch and some drinks. Rory first started writing "and thanks" but changed his mind and wrote in german words "und Danke" (same meaning). Later they went to Rudi`s home, where Rory discovered the Telecaster Rudi gave to him 1990.
21. May 1998, Rudi met the keeper of the inn of that time, and asked for the guestbook. After a while he found it in his cellar, and Rudi took the picture above.
