When he spoke with CBC Music earlier this year, Noel Gallagher was asked to review Supersonic, director Mat Whitecross’ new Oasis documentary on the group. “It's good,” he offered. “Brought back a lot of funny memories and how big we were and what an impact we made on people's lives and blah, blah, blah and all that. I'm not sure if anybody's gonna f--king learn anything from it.”

Below, we prove the man at the centre of one of music’s most bombastic acts wrong. Sorry Noel.

1. It only covers their glory years

Despite putting out music and anarchy for just under two decades, the documentary only charts the group’s rise to superstardom, up until their record breaking two-night residency at Knebworth in 1996; eschewing band member changes, the majority of their recorded catalogue, their rivalry with Blur and their relationships with women and their break up in 2009.

2. Liam and Noel’s rivalry began with a little drunken urination

Recalling their presumably teen days sharing a bedroom, Liam recalls, "One night I come in pissed and I couldn't find the light switch so I pissed all over his [Noel] new stereo. I think it basically boils down to that."

3. Liam didn’t care for music until he was struck with a blunt object

As a young hooligan, Liam crossed paths with an unfriendly gang who managed to smash him over the head with a hammer. While surely killing some brain cells, the event evidently knocked a passion for music into the young lad.

4. Noel wrote one their biggest hits in the time it takes to eat Chinese take out

In one particularly well illustrated scene, the elder Gallagher recalls writing the entirety of the group’s first single “Supersonic” in the studio as the rest of the band ate takeout in the room next door.

5. Crystal meth almost broke them up onstage during their first U.S. show

Riding high on the U.K. success, Oasis tried to take in their first American tour the best way they knew how. The night before their first gig, at L.A.’s legendary Whiskey a Go Go, the group snorted what they thought was cocaine but turned out to be crystal meth. Lacking any sleep, roadies mixed up each member’s setlist resulting in every member playing a different song at the same time. After the gig, Noel abandoned the band and shacked up with a groupie in San Francisco, returning with a new sense of purpose and a bigger stake in steering the band's career.
