So did Dave Gahan ("Ger-haan", though he's given up trying to standardise the Irish pronunciation) [2]. Conscious that he was nearing 30, always a recreational drug user and drinker, on the World Violation tour he deliberately set about transforming himself into the rock god-cum-monster of his more garish fantasies. Introduced to Jane's Addiction circles by Teresa Conway, previously the publicist on Depeche Mode's 1988 American tour, Gahan lost touch with the shiny-faced boy of old. He acquired long hair, a goatee and loads of tattoos; ten hours of pain went into the showpiece pair of wings that illustrate his shoulder blades.
To complete the picture, he took up heroin and left his wife, childhood sweetheart Joanne, and 5-year-old son Jack. Achingly aware that he emulated his own father's desertion when he too was 5, Gahan, now 34, contrives no excuses.
"My vision got cloudier and cloudier because of what I was putting into my body."
Feeling the pressure themselves, after the tour Gore and Fletcher went home to restore their resources with 'sane domestic life'. Their first children were born. Gore withdrew to the Hertfordshire countryside with his Texan-born wife, Suzanne, and, in due course, wrote Songs Of Faith And Devotion. With his wife, Grainne, the entrepreneurial Fletch opened a restaurant, Gascoigne's, in St John's Wood.
Gahan moved to Los Angeles and married Teresa Conway in a ceremony at the Graceland Chapel, Las Vegas, serenaded by the resident fake Elvis. Smitten with grunge, enraptured by Rage Against The Machine's metal/hip hop fusion, he thought about leaving Depeche Mode. Then Gore sent him a tape of the new songs. He loved them.
So he flew to Madrid to start recording. But when he met the band for the first time in several months, they just and stared at him. He remembers the moment.
"I'd changed, but I didn't really understand it until I came face to face with Al and Mart and Fletch. The looks on their faces battered me."
Deeply disorientated by Gahan's deliberate metamorphosis, for the very first time the four found that they couldn't work together. They took a break, then reconvened at the Chateau Du Pape, a residential studio in Hamburg. The shock that greeted the new Gahan had worn off. They adjusted and progressed.
"Dave would come forward on a real burst of energy, do a vocal, then disappear to his room for a couple of days. It was a bit odd," Fletcher notes with phlegmatic understatement.
Gahan thinks it was Wilder who eventually confronted him. "He used to do quite a bit of snooping around and he found some works in my room."
"Then we had our first ultimatum-meeting with Dave," continues Gore. "We said to him, You've got to sort yourself out. You're putting yourself in danger."
"They were genuinely concerned about my health," acknowledges Gahan. "Of course, I couldn't see that. I said to Mart, Fuck off! You drink fifteen pints of beer a night and take your clothes off and cause a scene. How can you be so fucking hypocritical?"
He stormed off to immerse himself in the pleasures of his addiction's honeymoon period.
But it was Fletcher, the commonsensical 'backbone' of the band, who came apart first. He had a nervous breakdown. Hospitalised for running repairs, he discharged himself too soon. The Songs Of Faith And Devotion tour, one of rock's great nightmares, was about to begin.
They took a therapist on the road with them. It didn't really work because, although Fletch saw him occasionally, the rest of us never did," chortles Gore. "After six weeks, we knocked it on the head." [3]
Songs Of Faith And Devotion was an instant Number 1 in the United Kingdom and America. Consequently, the tour grew and grew.
"For us, more workload means more partyload," Fletcher attests. "I know it's a cliche, but wherever you go, everyone wants to scream at you, photograph you, take you out. For the night, you're the kings of the city."
"When you finish a concert and every door is open to you, it's very hard to say, Actually, I'm off to bed," argues Gore. "I went to bed early once in fourteen months on that tour - at Park West, outside Salt Lake City."
He lets rip a rare unbridled guffaw at the thought that he can remember such a thing amid the mayhem.
Their personal dislocation worsened. They took to separate limousines as well as separate dressing-rooms - Gahan's was a fetid black-candlelit lair, whence, after the show, minions would cart his smack-blasted body back to the required hotel.
[2] - Aaargh! No! It's pronounced "Gaan". This is a common mistake in the press and one of Dave's pet hates (see here).
[3] - A psychiatrist and a drug dealer were part of the Devotional Tour entourage. One was used by Dave a lot, the other was intended for use by Dave. With hindsight, they perhaps knocked the wrong one on the head.
