When Liam was a kid he was called "Peggy's shadow" because he always clung to his mom. When Liam was around 8 years old, he said that he hated music. He would often insult people walking down the street with guitars in their hands. This is probably because his older brother Noel was quite afluent with guitars at the time and, because they shared a bedroom, they often fought with each other. Liam quit school around the age of 14 and became a fence-painter. He was making about $100 dollars a week while his former classmates were stuck in school, a fact which he found quite nice.

Around the time when Liam was 19, he hooked up with an old school buddy named Paul McGuigan. He found that Paul had a band that needed a vocalist, so he offered his services. When he joined, he changed the band's name from "The Rain" (which was the name of a Beatles song) to "Oasis"; a name which he apparently saw on a poster in his bedroom. Liam also became the band's song writer, along with Paul Arthurs (who was the also band's guitarist). They only really rehearsed one day a week and didn't get too many gigs. It was after one of their rare gigs, however, that Liam's older brother Noel saw them perform. He said that their band was "utter shite" and said that he would join if he took over control of the band and wrote all of their songs. The band agreed and, well, the rest is history.
