BBC Sport at Melbourne Park
When Andy Murray trudged out of the Melbourne Arena - now the John Cain Arena - three years ago, the DJ hit play on Joe Esposito's 'You're The Best'.
You'll know the song, especially if you're over 30. Or younger and a cult classic aficionado.
It is the one used for the montage at the end of The Karate Kid, the classic 1984 film, just after the protagonist Daniel LaRusso defies logic, defies expectation and defies injury to beat his opponent.
By chance or by choice, it felt apt.
In the end, Murray could not finish with a final flurry like LaRusso as he courageously lost to Spain's Roberto Bautista Agut.
But the story wasn't over. Murray has fought back from the hip surgery which he thought would end his career. Now the Scot is back on Melbourne Park's third show-court for a much-anticipated sequel.
