Last year, Sir Brian May spent his 77th birthday performing at one of Andrea Bocelli's annual Teatro del Silenzio concerts in Tuscany.
The Queen guitarist obviously had a great time as he returned this year for a "once-in-a-lifetime" duet.
During the concert this July, the two music stars performed Queen's iconic Who Wants to Live Forever.
Sir Brian famously penned the song for the band's A Kind of Magic album.
It was also part of the soundtrack for the film Highlander, about immortal warriors, which is being remade with Henry Cavill.
Five months after Freddie Mercury's death in 1991, Seal performed a live cover at The Freddie Mercury Tribute Concert.
Now, the full footage of Bocelli and Sir Brian's duet of Who Wants to Live Forever has been officially shared on YouTube. Check it out above.
