Making a name as a solo artist after having had a tremendous success as a duo is a daunting enterprise, but Georgios Kyriacos Panayiotou, best known as George Michael, passed that test with flying colors. He was already a superstar with Wham! but his 1984 debut solo single, Careless Whisper, made him a household name. Huge hits like I Want Your Sex and Faith only confirmed that impressive feat.
