Overview
- The surprise happened on Sunday, August 9, when Alexander Rier walked on during the live Immer wieder sonntags broadcast and sang his self‑written song “Von Mann zu Mann,” prompting a tearful reaction from Norbert Rier.
- Alexander has been covering his father on tour since Norbert’s 2025 health problems, a role Norbert praised on air as he expressed pride in his son’s performances.
- Norbert’s recent recovery follows a summer 2025 minor stroke and a heart‑valve operation in October 2025, with his staged return to performing earlier this year leading to the on‑air reunion.
- Producers kept Alexander hidden before the show to preserve the moment, and guests including Semino Rossi used the farewell season to deliver personal tributes that visibly moved host Stefan Mross.
- The August 9 episode drew about 1.28 million viewers and a 19.5 percent market share, the highest audience of the season, as the program continues its final live run through early September with a last regular edition on September 6 and a best‑of on September 13.
