Singer, songwriter, musician and actor Glen Campbell has died at the age of 81.

Campbell had been suffering from Alzheimer's Disease in recent years and embarked on a 'Goodbye Tour' in 2012 with three of his eight children joining him in his backing band. He died at his home in Nashville yesterday.

Throughout his long career - which spanned six decades - Campbell was known as a singer of note, most famously for his take on Jimmy Webb's 'Wichita Lineman' and 'By the Time I Get to Phoenix', and Larry Weiss's 'Rhinestone Cowboy'. He also hosted his own music and comedy variety show on TV in the late 1960s/early 1970s and appeared in several films, earning a Golden Globe nomination for his role in 'True Grit' in 1972.

He also battled addictions to cocaine and alcohol throughout his life, spending 10 days in jail in 2003 for DUI and leaving the scene of an accident.

He is survived by his fourth wife Kim Woollen and his eight children.
