<P> A symbol of the working class in the North of England, Brian Johnson customarily wears a newsboy cap on stage and frequently off . Johnson has occasionally worn baseball caps as well . His brother suggested that the singer wear the cap onstage to prevent sweat rolling off his thick, curly hair into his eyes while singing . "He said,' Put it on, at least you'll be able to see what the bloody freak you're doing!' So I put it on and after three songs in the second set, I looked at him, put my thumbs up --' This is brilliant!' He never did get that hat back ." </P> <P> In April 2016, during the Rock or Bust World Tour, AC / DC announced the departure of Brian Johnson citing hearing issues . As the band explained it, Johnson risked total hearing loss if he continued . Johnson stated that his hearing issues hadn't come from performing for 36 years with AC / DC, but from having forgotten to put ear plugs in during a race that left him with a punctured left ear drum . Guns N' Roses singer Axl Rose was recruited to complete the remaining 10 shows in North America and 12 shows in Europe . His last show with AC / DC was on February 28th, 2016; at the Sprint Center in Kansas City . After departing AC / DC, he recorded a new song with comedian Jim Breuer called "Mr. Rock'n'Roll". Johnson made a cameo appearance with rock band Muse on August 31, 2017, performing a rendition of "Back In Black" with the group . </P> <P> Since April 2003, Johnson, who says "I love musical theatre, especially the classic stuff, like Rodgers and Hammerstein", has been working on a musical version of Helen of Troy with Sarasota Ballet choreographer, Robert de Warren . The musical is a Les Misérables - style musical with rousing anthems, tender ballads and minimal dialogue . He conceived the project with writers Ian La Frenais, Dick Clement, and Brendan Healy after seeing Andrew Lloyd Webber's musical Cats and being underwhelmed at what he saw . </P> <P> Malcolm McDowell, who made his recording debut singing one of the songs for the soundtrack in Brian's studio, agreed to play Zeus . The Cranberries singer Dolores O'Riordan and Bruce Vilanch were also set to participate . In 2004 Johnson travelled to Greece to film an episode of the television series Goddess Odyssey in which he researched the Helen of Troy myth . It was released on DVD in July 2005 and contains music from the theatre production . Phil Carson, former chief executive of Atlantic Records, supported the project but it was never staged . </P>
