Isa Scott, the mother of legendary AC/DC singer Bon Scott, has died in Western Australia at the age of 94.

Undercover reports Isa remained one of AC/DC’s biggest fans and attended a show on every tour after her son Bon’s death in 1980; she last saw the band live as a VIP guest at the AC/DC show at Subiaco Oval on March 6, 2010.

Isabelle Cunningham Mitchell married Charles Scott in Scotland in the 1940’s. On July 9, 1946, son Ronald Belford was born.

Isabelle and Charles were known as Isa and Chick; Ronald became known as Bon.

In 1952, Isa and Chick, along with Bon and his younger brother Derek, migrated to Melbourne, Australia; in 1953, they had a third son, the Aussie born Graeme.

In 1956, the family moved to Fremantle in Western Australia, where Isa lived for the rest of her life.
