He also played on Lou Gramm's (from Foreigner) second solo album Long Hard Look. Campbell attended Rathmore Grammar School.
Sweet Savage was a NWOBHM band that Campbell joined when he was 15. The band members in Sweet Savage included Campbell on guitar, Trev Fleming on guitar, David Bates on drums and Ray Haller on bass and vocals. The band influenced Metallica, who covered the song Killing Time on their Garage Inc. covers album. In 1980 when Campbell was 18. In 1981 they released an e.p. consisting of four BBC radio sessions and their first single "Take No Prisoners". "Take No Prisoners" included the song "Killing Time". Much later in the late 90's after Metallica covered "Killing Time", there was interest in Sweet Savage and they released an album without him. Out on tour supporting bands like Thin Lizzy and Motorhead around Britain, Vivian caught the eye of bassist Jimmy Bain, who would soon join Ronnie James Dio to record his post-Black Sabbath solo debut for Warner Bros. In searching for a dynamic, powerhouse guitarist, Jimmy recalled his memorable impression of the young unknown Vivian, and recommended him to Ronnie. Vivian was 19 when he auditioned and that line-up went into the studio to record the now classic Dio albums "Holy Diver" and "Last In Line".
Thirteen Leppard years later the time finally came to pursue a solo album again, but this time the direction would take a different form. Living in Los Angeles, Vivian had immersed himself in the world of the local blues-club circuit, quite a change from the intricate arrangements, multi-overdubs and state of the art production values of Def Leppard. The spontaneity and "one-take" urgency of the true blues genre dictated a specific new set of rules that would be applied during the making of "Two Sides Of If." Rule number one: it had to be recorded LIVE in the studio, being sure to always maintain eye contact between all of the musicians. This meant Vivian singing lead vocals while playing solo guitar - no overdubs allowed..... Rule number two: have fun and fly by the seat of your pants. With wish-list players like Terry Bozzio on drums, and Billy Gibbons and Joan Osborne making guest appearances, the sessions were inspired and the end result is "Two Sides Of If." Twenty years in the making and not a minute too soon.
