Despite the success, Level 42 were on the brink of splitting up. Although Phil Gould was the most visibly dissatisfied member, it was Boon Gould who was the first to leave, departing in late 1987, following a support slot on a Madonna tour. The quietest member of the band, Boon surprised both King and Lindup with his sudden departure. However, he had been suffering from nervous exhaustion and also wanted to leave the lifestyle of a constantly touring musician in order to settle down and spend more time with his wife and children. Boon's relationship with the band remained amicable and, although he would not return to Level 42 as a performing or recording member, he continued to write lyrics for the band following his departure. He was temporarily replaced by Paul Gendler (an experienced session player who had previously been the guitarist for Modern Romance) for a six-week headlining tour and for further support slots with Tina Turner. In December 1987, midway through the tour, Phil Gould left Level 42 permanently. Like his brother, he was suffering from exhaustion, but his relationship with King had broken down once again and they now found it difficult to work together. Phil was also reportedly dissatisfied with the band's direction in terms of their newer "pop" sound, and King and Lindup failed to convince him to stay. To complete the tour dates, the band hired Prefab Sprout drummer Neil Conti to fill in. Following the tour, Level 42 recruited Gary Husband as the band's new full-time drummer. He in turn recommended Steve Topping as a replacement guitarist. However, Topping and King's personalities clashed and Topping eventually left the band in early 1988 after initial writing and rehearsing sessions in Dublin. Most of the next Level 42 album, "Staring at the Sun", was recorded without a permanent guitarist. Rhythm guitar on the studio recordings was handled either by the band's old friend Dominic Miller or by an uncredited Mark King. In April 1988, towards the end of the sessions, the band recruited lead guitarist Alan Murphy (a session guitarist who had worked extensively with Kate Bush and had also been a member of Go West). "Staring at the Sun" was released in 1988, reaching number 2 in the UK and the top ten in several European charts. It included the hit-single "Heaven in My Hands" (number 12 in the UK and also top twenty in the Netherlands, Norway, Switzerland). Boon Gould had co-written many of the tracks with King, Lindup and Badarou, while Gary Husband was credited with his first co-write with King on "Tracie" (a tribute to King's childhood sweetheart).
