Freddie Mercury and Elton John are true icons, stamping their mark on music and the world with remarkable careers.
Both hitmakers of the 1970s and beyond, it seemed natural that the two meet on more than one occasion.
That they became such close pals was a match made in showbiz heaven - two larger than life characters, beloved by millions, came together in a friendship that lasted across decades.
Freddie tragically died in 1991, after a secret battle with Aids, only telling the world of his medical status hours before his final breath.
Recent revelations by Elton, now 73, have given fans a glimpse into the relationship that became so strong that he was one of the few people Freddie allowed to see him as he lay dying.
Elton describes Freddie's final days in his memoirs - during which the Queen frontman never lost his sense of humour or kindness.
"He was too frail to get out of bed," the Rocketman singer recalled.
"He was losing his sight, his body was covered in Kaposi's sarcoma lesions, and he was still definitely Freddie, gossiping away, completely outrageous."
This was Freddie down to a tee, says Elton, and he'd been the same since they first met back in the '70s.
Since their first meeting, they'd been through a lot together - Elton experiencing addiction issues in '80s.
It was Freddie, in fact, who led the charge among Elton's celeb pals to get him to kick his cocaine habit, and encouraged him into rehab.
Elton told that his addiction issues had stemmed from a struggle with fame and an emotionally tough childhood - but Freddie was there to point him in the right direction.
And Elton was just as committed to Freddie, starstruck by his iconic onstage performances.
He told The Guardian of Queen's Live Aid performance in 1985, often considered the greatest live gig of all time.
"I had a huge area that I kind of decorated. I made sure there were seats for everyone, so that people who were playing could sit down and have a natter.
"Freddie came over after Queen had stolen the show.
"I said, 'Freddie, nobody should go on after you, you were magnificent."
With a cheeky smile, Freddie came back: "You're absolutely right, darling, we were. We killed them."
Elton also recalled that Freddie never failed to be exceedingly generous, even on his deathbed.
"On Christmas morning," he remembered, "[Musician] Tony King came round and gave me this pillow case....my drag name is Sharon and Freddie was Melina.
"In the beautiful pillowcase was a watercolour painting.
"In the note that went with it, it said, 'Dear Sharon, I saw this at auction and thought you would love it. I love you, Melina."
Elton still has the painting, and the pillowcase.
