According to Wikipedia:
Oasis evolved from an earlier band called The Rain....Liam suggested that the band name be changed to Oasis. This change was inspired by an Inspiral Carpets tour poster which hung in the Gallagher brothers' bedroom. One of the venues the poster listed was the Oasis Leisure Centre in Swindon.
Yeah, Oasis in the Gallagher brothers' bedroom. Odd beginning, and an odd end.
