AC/DC singer Brian Johnson joined MUSE on stage Sunday night (August 27) at the Reading Festival in England to perform his band's iconic track "Back In Black".
Johnson appeared with the trio on stage at the start of the encore. MUSE frontman Matt Bellamy told the crowd: "He's back!" before they launched into the AC/DC classic.
"Thank you so much. Thank you, boys," Johnson said at the end of the song, hugging Bellamy.
Tonight's appearance was Johnson's second time on stage since leaving AC/DC in March 2016 due to hearing issues.
Back in May, Johnson and LED ZEPPELIN frontman Robert Plant joined Paul Rodgers for an encore performance of Barrett Strong's 1959 classic "Money (That's What I Want)" in Oxford, England.
AC/DC postponed the last ten dates of its North American tour last year after doctors told Johnson he faced a total loss of hearing if he did not stop touring immediately. AC/DC completed the tour last summer, with GUNS N' ROSES singer Axl Rose as a "guest vocalist" and Johnson apparently not returning to the group.
Johnson said in an open letter to fans that he intends to solve his hearing problem and continue recording and touring, although he pointedly did not say whether he would be rejoining AC/DC.
The vocalist wrote: "My entire focus is to continue medical treatment to improve my hearing. I am hoping that in time my hearing will improve and allow me to return to live concert performances. While the outcome is uncertain, my attitude is optimistic."
