Chicago is an American rock band formed in 1967 in Chicago, Illinois. The self-described “rock and roll band with horns” began as a politically charged, sometimes experimental, rock band and later moved to a predominantly softer sound, generating several hit ballads. The group had a steady stream of hits throughout the 1970s and 1980s. Second only to the Beach Boys in Billboard singles and albums chart success among American bands, Chicago is one of the longest-running and most successful rock groups, and one of the world’s best-selling groups of all time, having sold more than 100 million records.
According to Billboard, Chicago was the leading US singles charting group during the 1970s. They have sold over 40 million units in the US, with 23 gold, 18 platinum, and 8 multi-platinum albums. Over the course of their career they have had five number-one albums and 21 top-ten singles.
Andrew Roy Gibb was born on 5 March 1958 in Manchester, England. He was the youngest of five children of Barbara and Hugh Gibb. His mother was of Irish descent and his father was of Scottish and Irish descent. He has four siblings, his sister Lesley and three brothers, Barry and fraternal twins Robin and Maurice.
At the age of six months, Gibb emigrated with his family to Queensland, Australia, settling on Cribb Island just north of Brisbane. After moving several times around Brisbane and Sydney, Andy returned to the United Kingdom in January 1967 as his three older brothers began to gain international fame as the Bee Gees.
In his childhood, his mother Barbara described Gibb as “A little devil, a little monster. I’d send him off to school but he’d sneak off to the stable and sleep with his two horses all day. He’d wander back home around lunchtime smelling of horse manure, yet he’d swear he had been at school. Oh, he was a little monkey!”.
