During this decade, Harry Klynn was undoubtedly the top name in the big night clubs. He collaborated with practically every major artist in the music business ( to name but a few: Stelios Kazantzidis, Marinela, Stratos Dionisiou, Poli Panou, Filippos Nikolaou, Dimitra Galani, Viki Mosholiou, Lakis xalkias, Manolis Mitsias, Dimitris Mitropanos, Giannis Parios, Giannis Poulopoulos, Tania Tsanaklidou, Elpida, Haralambos Garganourakis, Antonis Kalogiannis, Eleni Vitali, Haroula Alexiou, Anna Vissi, Pashalis etc).

Among the numerous shows he put up in the clubs of Plaka, those which really stand out would be the ones hosted at “Diagonios” Club, namely “Aishos” (Disgrace) which he wrote together with Yiannis Kakoulidis and music composed by Takis Bougas, and “Allagi kai Pasis Ellados” (Winds of Change over Greece) where Nikos Stratigos was the one to compose the music. Equally famous and successful proved to be his shows at “Zigos” club, namely “Korioi” (Bugs), “Natin – Fatin” (You eat it, cause here it comes!) and “Ethniki Kseftilas Geia sou” on whose script and music he worked again with his old partners Yiannis Kakoulidis and Nikos Stratigos.

His music shows at “Diogenis”, “Dilina”, “Stork” and “ Neraida” changed our notion of  nightly entertainment for ever.
