Formed in January 1981, the band was originally known as Le Hoodoo Gurus for the release of their first single, "Leilani", in October 1982.  As Hoodoo Gurus, the band signed with Big Time Records and premiered their debut album, "Stoneage Romeos", in March 1984.  Also issued in the United States through A&M Records, the record remained atop the Alternative/College Albums Chart for four consecutive weeks, with it also becoming one of the most played albums of that year on the college network.  The group's subsequent albums, "Mars Needs Guitars! ", "Blow Your Cool! " and "Magnum Cum Louder", all reached the "Billboard" 200. Oasis were an English rock band formed in Manchester in 1991.  Developed from an earlier group, the Rain, the band originally consisted of Liam Gallagher (vocals and tambourine), Paul "Bonehead" Arthurs (guitar), Paul "Guigsy" McGuigan (bass guitar), and Tony McCarroll (drums, percussion).  They were later joined by Liam's older brother Noel Gallagher (lead guitar and vocals) as a fifth member, becoming the band's settled line-up until April 1995. Hoodoo Gurus (referred to as the Gurus by fans) are an Australian rock band, formed in Sydney in 1981, by the mainstay Dave Faulkner (songwriter, lead singer and guitarist) and later joined by Richard Grossman (bass), Mark Kingsmill (drums), and Brad Shepherd (guitar, vocals, harmonica).  Their popularity peaked in the mid to late 1980s with albums "Mars Needs Guitars! ", "Blow Your Cool! " and "Magnum Cum Louder". The Dubrovniks were an Australian rock band which formed in August 1986 as The Adorable Ones.  Early in 1987 they changed their name, which acknowledges two of their founders, Roddy Radalj and Boris Sujdovic, birthplace in Dubrovnik, a town in Croatia.  Both Radalj and fellow founder James Baker had also founded Hoodoo Gurus (as Le Hoodoo Gurus) in 1981.  All three had earlier associations in the Perth punk scene of the late 1970s.  The group issued four albums, "Dubrovnik Blues" (August 1989), "Audio Sonic Love Affair" (September 1990), "Chrome" (June 1992), and "Medicine Wheel" (1994), before disbanding in 1995. "Leilani" was the first single by iconic Australian rock group Hoodoo Gurus when they were called Le Hoodoo Gurus and was released on Phantom Records in October 1982.  It had been written by all four Gurus: James Baker, Dave Faulkner, Roddy Radalj and Kimble Rendall.  Rendall left shortly before its release and, not long after, the band dropped the 'Le' to become Hoodoo Gurus.  Le Hoodoo Gurus were noted for having three guitars and no bass player, creating a distinctive, layered sound.  This was captured on "Leilani", which told the story of a maiden sacrificed to the gods and an erupting volcano while her true love looked on helplessly.  The song was later released on Hoodoo Gurus' first album "Stoneage Romeos" (1984).
