In March 2007, it was announced on the Stranglers' website that Black was suffering from
atrial fibrillation and consequently refrained from appearing with the band until he had recovered. He returned to playing with the band in June, but he permanently retired from performing outside of the United Kingdom due to the strain of lengthy travel. During Black's absences, his temporary replacement was his full-time drum technician Ian Barnard (born 1983). In mid-2008, Black was again absent from several Stranglers gigs. It was shortly thereafter announced that he was suffering from chest problems and was "not rushing back to work" on the advice of his doctor. In September 2008, he returned to full rehearsals and began touring with the band on 13 October. During the Stranglers' 2010 and 2011 UK tours, Black performed at every gig. He played the full sets, which were approximately 90 minutes in length. On 12 March 2012, Black was taken to hospital after "falling ill" shortly before a Stranglers concert at the O2 Academy Oxford. He was again replaced by Barnard during the gig. The Stranglers announced the following day that he had been taken to hospital via ambulance after feeling unwell shortly after the band's soundcheck. It was confirmed that the illness was a "severe chest infection" but that Black intended to rejoin the tour when he was "fit and able"; he did not rejoin the tour due to a slow recovery. The Stranglers' annual tour began in March 2013, with Black playing the second half of the opening night set, drumming on 10 songs beginning with the distinctive Genetix drum intro. Drummer Jim Macaulay played the first half of the set on a separate, smaller drum kit. He had also by this time completely refrained from travelling outside of the UK with the band. Black did not feature at some subsequent gigs, but played half of the band's set at others where stage space would allow for the positioning of two drum kits. Jean-Jacques Burnel said ahead of the band's Leeds gig: "He's had a few health problems in recent years, but he's really up for the tour, although he probably won't be at every gig or doing the full set". His appearances during the 2014 Ruby Anniversary tour were sporadic. When present, his playing was restricted to the encore only. During the tour, he was quoted as saying: "I'll carry on until I'm incapable of doing it. I am going to have to stop one day, but I expect the band will carry on". The bassist, Jean-Jacques Burnel, said during the same period, "When he can [no] longer contribute – and I don't think that's long – then there will be no more Stranglers". He remarked that Black was "on oxygen" even after drumming on slower numbers like "Golden Brown". In 2014, Black said of the Stranglers: "This is the best band in the world — and we'll carry on until we can't any more. Though we are not thinking about that". He was absent from the Stranglers' UK festival appearances and associated warm-up gigs in mid-2014. In January 2015, Stranglers guitarist Baz Warne told the
Louder Than War website: "Jet will do what he can when he can. He's a massive hard worker and he's never shirked away from anything but with the best will in the world you just can't cheat old age. I know a lot of the old fans say it's not the same without Jet, and they're absolutely right but there comes a time when you have to ask yourself a simple question; do you want to see The Stranglers without Jet or just accept that you'll never see them again?" Black's final appearance on stage with the Stranglers was at the
Cambridge Corn Exchange on 20 March 2015. ==Retirement==
