What was the original name of the British pop group Oasis?

Oasis evolved from an earlier band called The Rain, who took their name from a 1966 Beatles B-side. It was comprised of Paul "Guigsy" McGuigan (bass guitar), Paul "Bonehead" Arthurs (guitar), Tony McCarroll (drums) and Chris Hutton (vocals). When McGuigan invited school friend Liam Gallagher to join the group, Gallagher accepted, and quickly pushed for the band's name to be changed to Oasis. Although there have been many theories on where Liam got the name from, he got it from an Inspiral Carpets tour poster which was in his and Noel's bedroom. One of the venues on it was the Oasis Leisure Centre in Swindon.
