AC/DC singer Brian Johnson joined rock and roll icon Mick Fleetwood on stage on March 4 at Fleetwood's On Front St., a restaurant and bar owned by Fleetwood in Maui, Hawaii, to perform the 1940s rhythm and blues standard "(Get Your Kicks On) Route 66". Video footage of his appearance can be seen below.
Johnson was forced to leave AC/DC in March 2016, midway through its world tour in support of "Rock Or Bust", after doctors told him he faced total hearing loss if he continued to perform live. His replacement for the balance of the dates was GUNS N' ROSES frontman Axl Rose.
Johnson joined AC/DC in 1980 following the death of vocalist Bon Scott. He made his debut with the band on that year's "Back In Black" album, one of the most successful LPs of all time.
The rock legend and car aficionado spoke to The Sunday Times about his passion for the most magnificent four-wheeled vehicles in history and he also touched upon the hearing problems that ended his 36-year career with AC/DC.
"On stage, it was getting harder and harder to hear the guitars, even hear the keys, and I was basically going on muscle memory," Brian said. "And I'm not the kind of guy who likes to cheat. The way I look at it, I had a great run."
Two years ago, Johnson said in an open letter to fans that he intended 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."
AC/DC's future remains in doubt after the band completed its last world tour, a cycle that saw a massive turnover in the group's personnel. Guitarist Angus Young has not yet indicated whether the group will continue recording and touring.
The lineup that completed the tour consisted of Young, Rose, bassist Cliff Williams, Chris Slade on drums and Angus's nephew Stevie Young on guitar.
