At Flat Iron Square in London, where 650 people crammed in to watch on a giant screen, the party began with beer showers and chants of "Football's coming home" after the 2-0 win over Sweden in Russia.
Friends leapt on one another's shoulders to belt out the song from the 1996 European Championships, an uplifting Britpop anthem of maintaining hope against precedent.
"I've been going thirsty to the well of pain for a long time," said long-suffering fan Stephen Walter, 42, from north London.
"Now we're a well-organised team, there's a good feeling all round, the flags are flying again. The stars seem to be aligned!"
Steve Richardson, 50, a sales director from Cambridge in eastern England, said he told his 22-year-old son he would "never experience this again in his lifetime, let alone mine.
"We could actually win this. This is exactly what the country needs. I absolutely believe we will be world champions.
"I've seen it for 50 years and we've always fallen. This is it!"
Three long decades
The last time England reached a World Cup semi-final was at Italy 1990, when 16 of the current squad were not even born.
It was closer in time to England's 1966 World Cup triumph than today.
Margaret Thatcher was Britain's prime minister. Phones were coin-operated, came in red boxes and people queued to use them.
The 1990 squad starred Gary Lineker, John Barnes, Chris Waddle and Paul Gascoigne. Peter Shilton, England's goalkeeper then, is now 68.
In Flat Iron Square, in scenes mirrored across the country, many had the England flag -- Saint George's red cross on white -- painted on their cheeks, and while many men wore replica England shirts, many more stripped off in the baking 30 degrees Celsius (86 degrees Fahrenheit) heat.
An air horn went off to cheers at the first appearance of the teams in the tunnel and "God Save The Queen" was belted out in a full-throated rendition.
A tight first quarter quietened the mood but the place erupted in the 30th minute when Harry Maguire headed in England's opening goal with beer flying everywhere, gallons raining down as people roared in celebration.
At half-time, Camilla Mosley, 24, from London, said: "If we win the World Cup, I will shower in beer for the rest of the year."
'England till I die!'
She did not have to wait long for the next dousing when Dele Alli doubled England's lead and the drinks went flying once again and people clambered on the tables as they bounced around in delight.
The goal triggered chants of "I'm England till I die" and as full-time approached, any nervousness evaporated and the party could really begin.
At the final whistle, people bounced erupted in wild jubilation once again, with beer, clothes, barriers and bodies tumbling to another deafening chorus of "Football's coming home!" as flares went off and passing truck drivers honked their horns.
"I've never seen us so good. This is something different. The whole nation is going crazy. It's chaos. I've never been so soaked in beer!" said south Londoner Tony, who turns 28 on Sunday.
Adam Clayton, 38, wearing a replica of Gascoigne's 19 shirt from the 1990 World Cup, recalled the long wait to let rip.
"Words can't describe it. It's insane. I think it is actually coming home! I seriously believe so! Many a tear. We've had a nice run of the draw, which is right for England after the terrible times we've had," the Arsenal fan said.
Public relations worker Tania Burnham, 27, said: "The atmosphere is amazing. I'm covered in beer, but I'll take it because it's coming home."
