Heino – 81
Heino is one of the most successful German singers in history and has sold millions of his albums over the course of his career. While it makes it look more presentable and avant-garde, there is a reason for its characteristic black glasses look. He has an illness called exophthalmos, which causes one of his eyes to appear arched. Heino recently announced his upcoming tour later this year, although he only announced his retirement last year. Looks like Heino hasn’t finished his musical journey yet.
