Occasionally, and especially for more prestige engagements, this original vocal 3-piece teamed up with local instrumental outfits, including The Vector Men and The Hurricanes. Typical of the era, the Hurricanes had started out as a Shadows-style instrumental act, but the impact of The Beatles and other "British Invasion" bands saw many guitar bands around Australia recruiting lead singers and changing over to vocal-based material. The Twilights and The Hurricanes developed a solid bond, leading to the formation of the six-piece, fully electric-and-vocal group, The Twilights. Still based in Adelaide, and originally self-managed and produced, the band released its debut single, "I'll Be Where You Are" on EMI's Columbia imprint in June 1965. A ballad written by Shorrock and Britten, the single gained some airplay in Melbourne but failed to chart outside Adelaide. Subsequent singles made further inroads – the second release, "Wanted To Sell", cracked the Melbourne charts and the third, the brisk, Beatles-styled Brideoake/Britten original "If She Finds Out" gave the band its first chart success in Melbourne, Sydney and Brisbane. The Twilights quickly gained a strong reputation for their dynamic live shows in Adelaide. Early in 1965, drummer Frank Barnard left the group after the band hired Gary Spry as their manager. Barnard was replaced by Laurie Pryor, a well-known local drumming prodigy, who had previously played with another popular Adelaide band, Johnny Broome & The Handels. The new Twilights line-up with Pryor remained intact for the rest of the life of the band. After taking over the group's management, Melbourne promoter Gary Spry realised that it was essential to establish the group in Australia's pop capital, Melbourne. The Twilights moved there in late 1965 where they took up a three-month residency at Spry's discothèque, Pinocchio's. Their reputation quickly spread around Melbourne; the club was sold out every night and they were soon being booked by all the major disco and dance promoters in the city. The band's first recording after relocating to Melbourne was a version of the Animals song "Baby Let Me Take You Home", which marked the beginning of their successful collaboration with EMI house producer David Mackay; it gained a minor chart placing in Melbourne but made no impact in other cities. The Twilights fared much better with their next two releases. Their fourth single was a cover of Larry Williams' "Bad Boy" (June 1966), a track made famous by The Beatles; a video recording of the group performing this song on the pop program "The Go!!
