Rumor has it that Prince, otherwise known as The Artist Formerly Known as Prince, is teetotal, although maybe it is hard to believe. All Google searches for Prince in association with drugs led to Saudi sheikhs, cocaine and beheadings (not kidding), so I can only believe what the rumors say. Actually, it is a little above rumor, since many sources say that his father, John Nelson, was also teetotal, and he looked up to him, growing up. It is likely that he had never drank, and is vegan besides. For Prince to be this creative for so long (complete with his current project, called Third Eye Girl), it would not be believeable to hear he was doing drugs for the past three decades.
Elton John’s biggest demon was never really booze, most of his demons seem internal. He was given to depressive episodes where others would find him hard to cope with, but later he would come to his senses and make it up to his colleagues, often producers, engineers and fellow studio musicians. About 40 years ago, he suffered a drug overdose and later suffered from bulimia. He also had to battle feelings of suicide on many occasions. In 2015 he celebrated his 25th year of sobriety and freedom from drugs. At age 68, 20 years after being inducted into the Songwriters’ Hall of Fame, he has been awarded most of his Grammy Awards and Tony Awards only since the 1990s, long after he reached rock superstardom in the mid-1970s.
