Amid the driving rain and flashes of lightning, Usain Bolt breathed new life into the 100 metres by defeating two-time former drug cheat Justin Gatlin to take gold at the World Championships in Moscow.
The world record holder defied the atrocious conditions to blaze to victory on a drenched blue Mondo track at the Luzhniki Stadium in 9.77 seconds, his best time of the year.
He held off the challenge of Gatlin, who clocked 9.85secs, with Bolt's fellow Jamaican Nesta Carter getting bronze in 9.95s.
Bolt performed all his customary pre-race preening, pretending to hold up an umbrella, all part of the show from the born entertainer but when it came to the crunch he was, as always, ice cold.
He was out of the blocks well and, just as it looked as if Gatlin, in the lane inside him, might be closing, he pulled clear to reclaim the title he lost after that sensational false start in the final in Daegu two years ago.
Bolt said: "It was not a revenge for Daegu, I just came here to win this title.
"I wanted to do a better time, but was not able to because of the weather. This is just one of those days - not 'singing in the rain', but 'running in the rain'."
Gatlin added: "We saw the lightning on the horizon when we were on the warm-up track. Then we saw the tent rattling and I thought they were going to postpone the race."
It takes more than the a spot of thunder to put Bolt off his game, though.
This final had been headed for a mouthwatering showdown between Bolt and a rejuvenated Tyson Gay, before the latter's failed drug test sent shock waves through athletics. Former world record holder Asafa Powell's failed test was confirmed hours later and the sport was on its knees.
So it was perhaps apt that tonight's race was a head-to-head between Bolt, the saviour of the sport, and Gatlin, who has twice served drug bans, including a four-year suspension, which ended in 2010.
The American had beaten Bolt by a whisker at a Diamond League meeting in Rome at the start of the season, but the world stage is where the world record holder feels at home.
He said: "It was an average start and that, for me, is a great start. Around great starters like Gatlin and Carter I knew I had to get it right. I knew Gatlin was not going to crack under pressure so I had to stay focused and run to the line.
"I said to Gatlin I always appreciate competing with him because he always comes out and gives it his best."
Gatlin added: "He's a competitor and a showman. He's a gamer. If you're going to get beaten then get beaten by the best."
Bolt had sauntered through his semi-final in 9.92 earlier tonight, along with three compatriots. In the end there were four Jamaicans in the top five, with Kemar Bailey-Cole fourth in 9.98 and Nickel Ashmeade fifth in the same time.
It is difficult to imagine what the next serving from a "living legend", as Bolt branded himself after his triple London 2012 triumph, will be, but everyone's favourite Jamaican is on his way there.
By his own stratospheric standards, Bolt had between below par this season, his best time the 9.85 he ran to win the London Anniversary Games.
He is, though, quite simply on another level to his competition when it matters, and it showed.
"I am going to try continue winning championships. I want to be mentioned alongside greats like Pele, Maradona and Muhammad Ali," he said.
And that could include the Commonwealth Games in Glasgow next summer.
"I have never been to the Commonwealth Games," he said. "It's something I'm thinking about, but I don't know if I'm going to go yet. It would be something to add to my resume."
The only negative was the fact that, yet again, the stadium was some way off capacity, hugely disappointing given tonight's action included everyone's favourite Jamaican and an appearance by Russian darling Yelena Isinbayeva in pole vault qualifying.
Tickets were still available for the 100m final for 300 Roubles (£5.88) just two hours before the blue riband event got under way.
