The group performed at Wembley Stadium on July 13, 1985; a set that went down in history as one of the greatest of all time.
Now, 34 years later, May has posted about it – saying that, had frontman Mercury not died in 1991, he would likely still be doing what Roger Deacon and May himself are still doing today: performing.
Taking to Instagram, he posted a photo of himself and Mercury on stage.
“As I watch the Sun go down in San Francisco tonight, I ponder how I felt on that sunset 34 years ago – after we’d played Live Aid in the Old Wembley Stadium in London Town,” he captioned it.
“Little did we know how those few minutes on that day would reverberate down through time. So many sunsets since then.
“And I know for certain that if our dear bro’ Freddie we’re still with us, he would, like us, still be out on the road, far from home, giving it all in pursuit of the roar of a crowd – a crowd of folks who, like us, feel something special stirring in their bodies, and want to celebrate it.
“34 years later, why am I here ? Why are we here ? Because this is what we do.
“I’m still grateful, and somehow still 100 per cent driven.”
He added: “Yep – it was all worth it. Thanks for that roar, folks #liveaid #queen #sunset.”
May and Taylor are currently touring North America with vocalist Adam Lambert on their huge Rhapsody Tour, which moves to Asia and Australasia in early 2020.
The band’s Live Aid set was the big moment in Bohemian Rhapsody; the Queen movie biopic that broke records upon its release last year.
It was the first thing that was filmed for it; with Rami Malek – playing Mercury – speaking fondly of his time recreating that moment.
“I was somewhat prepared, but no one can ever prepare you for what that feeling was like, what some consider the greatest performance in rock history,” he told Deadline.
Live Aid was a benefit concert held simultaneously at Wembley Stadium in London and the John F Kennedy Stadium in Philadelphia.
It had an estimated total audience of around 1.9 billion across 150 nations – about 40% of the world’s population.
The likes of David Bowie, U2, Sting, Sade and Ultravox also performed in the UK; while Led Zeppelin, Patti LaBelle, Eric Clapton and Madonna sang in the US.
