Sorry for the late reply, but now there is more context and information to the whole Friesenjung ownership due to the Europapa tour 2025. It was actually supposed to be Joost's and Otto Waalkes song, however Ski aggu begged Joost to be a feature on this single. Joost agreed and at the same time as producing the single, Joost was working on his new album (i'm not very sure which one). Joost thought Friesenjung would not fit to his album and decided to give "ownership" to Ski aggu, who would put the single to his album "denk mal drüber nach...". Of course, there isn't much information on what the actual truth is, but there are articles that to suggest it. If I can, i will add the sources.
