Udo Lindenberg mourns longtime friend Clemens Buss

German rock singer Udo Lindenberg, 80, announced on Instagram on 31 July 2026 that his oldest friend Clemens “Clemi” Buss had died on 25 July. The two grew up as neighbours on Gartenstraße in the Westphalian town of Gronau, formed a school jazz band and remained close for almost eight decades. Lindenberg shared a black‑and‑white photo of the pair and wrote, “Clemi and Udo, the boys from Gartenstraße – my longest childhood friend,” adding hopeful words: “We will see each other again. In heaven there is also a Gartenstraße.” The tribute came as Lindenberg was already dealing with health issues that had forced him to cancel recent performances, including the Panikpreis concert in Calw. The post drew widespread attention in German media, highlighting the deep personal loss of a cultural icon.
