The 'Cocktail Trio' was a Dutch vocal trio active in the 50's-70's. Popular songs of them include 'Het Vlooiencircus', 'Op een Kangeroe-eiland', Batje Vier (Leve de man die het bier uitvond) and 'Wie heeft de sleutel van de jukebox gezien?'. The founder and leader of the group was Ad van de Gein('s-Hertogenbosch, 18th of may 1922). He also wrote songs for Willeke Alberti ('Morgen ben ik de bruid') and Ria Valk('de Vrijgezellenflat') that became hits in the Netherlands. The original group ended in 1979, because Ad van de Gein was diagnosed with cancer, and was unable to perform anymore. He was replaced by Henny Langeveld. Ad van de Gein tried to claim the rights for the name 'Cocktail Trio' in 1982, but failed. The group disbanded in 1985 with the death of original member Tonny More. In the last few years the remaining members of the group, including a recovered Ad van de Gein, have performed on occasion for a few times.
