ZDF announces hit cast for “Roland Kaiser Show’: A name on Giovanni Zarrella’s guest list is irritating. On stage are, among others, Beatrice Egli (35), Kerstin Ott (42), Melissa Naschenweng (33), Semino Rossi (61), Thomas Anders (60), Nino de Angelo (60) Maite Kelly (44), Bülent Ceylan (48) and Mary Roos (75) The latter is likely to raise some questions as she announced her retirement in February 2019.
