How did Oasis (band) get their name?

Oasis evolved from an earlier band called the Rain, composed of Paul McGuigan (bass guitar), Paul Arthurs (guitar), Tony McCarroll (drums) and Chris Hutton (vocals). Unsatisfied with Hutton, Arthurs invited and auditioned acquaintance Liam Gallagher as a replacement. Liam suggested that the band name be changed to Oasis. This change was inspired by an Inspiral Carpets tour poster that hung in the Gallagher brothers' bedroom. One of the venues the poster listed was the Oasis Leisure Centre in Swindon, Wiltshire.
