It's been sung loud and proud countless times across England in recent weeks.
And tonight, as our heroes line up against Italy, the nation will belt out Three Lions once again.
Even if you're not a football fan - and have drowned out the chatter of the last few weeks - you're still likely familiar with the lyrics to the 1996 hit, courtesy of David Baddiel, Frank Skinner and the Lightning Seeds.

But it turns out a lot of us aren't as familiar as we think we are, the Mirror reports.
People have taken to social media to tell of their shock at getting the chorus lyrics wrong - having been corrected by friends and family.
Many of us - for years - have always sung:
Cause I remember three lions on a shirt!
Jewels remain still gleaming,
Thirty years of hurt,
Never stopped me dreaming.
The actual lyrics are...
Cause I remember three lions on a shirt!
Jules Rimet still gleaming,
Thirty years of hurt,
Never stopped me dreaming.
The Jules Rimet trophy was the name of the original World Cup trophy - after the third ever FIFA president who served between 1921-54.
It was the trophy the English side won back in 1966 but was stolen four months before England won it
A week later, docker David Corbett was walking his collie Pickles in Norwood, South London, when the clever pooch found the trophy hidden under a car.
Corbett was given a £6,000 reward and attended the players' celebration dinner after England jubilantly lifted the trophy.
