Background: Rose Tattoo is an Australian rock and roll band, now led by Angry Anderson, that was formed in Sydney in 1976. Their sound is hard rock mixed with blues rock influences, with songs including "Bad Boy for Love", "Rock 'n' Roll Outlaw", "Nice Boys", "We Can't Be Beaten" and "Scarred for Life". Their first four albums were produced by Harry Vanda and George Young who also worked with AC/DC. They disbanded in 1987, subsequently reforming briefly in 1993 to support Guns N' Roses on an Australian tour.
Context: Anderson mounted his solo career from mid-1987. He released the ballad, "Suddenly" as a single. It was taken from Beats from a Single Drum, which was then re-released as his debut solo album in 1988. "Suddenly" had little chart success until it was used on television soap opera, Neighbours for the wedding of characters Scott Robinson (Jason Donovan) and Charlene Mitchell (Kylie Minogue). "Suddenly" peaked at No. 2 in September 1987 and was kept out of top spot by Minogue's debut single, "Locomotion". In the early 90s, Anderson tried to reunite Rose Tattoo, but the death of Royall, who died in 1991 of cancer while trying to overcome substance abuse in the form of a heroin addiction and alcoholism, stalled the reformation.  In an interview with Australian journalist Nick Milligan on 25 March 2011, Anderson explained, "I was in Los Angeles in 1989 recording an album which the 'Bound For Glory' single came off and I was hanging around with the Gunners and a lot of other LA bad boy rock bands that we supposedly influenced. I realised then that apart from the fact that I was there to establish myself as a singer songwriter, there was still this great following for the band. I rang up the other members and said 'Let's reform. We've been apart for three years or more.' It was long enough for us to settle our differences and let all the wounds heal. I rang up each of the original members that were still interested and they all said, 'Yeah, let's get together.' So I said we should negotiate a deal where the band can come over and record in Los Angeles. But, of course, that was the year that our original drummer "Digger" Royall kicked his heroin habit. While he was recovering on methadone, cancer exploded through his body, quite sadly. That was the irony of it, because the cancer had been suppressed by the heroin addiction. Within months he was dead. That shook the band so badly on a personal level, because we had been so enthusiastic to reform. We didn't reform until '92. In '93, the word got around, because we had reformed with our existing drummer Paul DeMarco. The Gunners heard we were out playing again and said, 'We want you to do our support gigs throughout Australia.' We did those two Guns N' Roses raceways gigs - Eastern Creek in Sydney and the raceway down in Melbourne."  Rose Tattoo supported Guns N' Roses on the Australian leg of their Use Your Illusion Tour. Anderson, Wells, Cocks, Leach and new drummer Paul DeMarco from Wells' solo band reunited for the 1993 tour. The reunion was brief and each returned to solo projects.  Around this time, ex-members of Rose Tattoo formed a short lived band with ex-Candy Harlots vocalist Aiz Lynch. This band had numerous rehearsals, but only recorded one demo before disbanding.
