Oasis were an English rock band formed in Manchester in 1991. The band originally consisted of Liam Gallagher, Paul "Bonehead" Arthurs, Paul "Guigsy" McGuigan, and Tony McCarroll. They were joined later that year by Liam's older brother Noel Gallagher as a fifth member.
Stewie's Sherlock Holmes details their murder case in "V is for Mystery", noting that two toothless people had filthy sex in an alleyway and would become the grandparents of the "two guys from Oasis," with a screenshot of Liam and Noel.
