They downed tequila shots and danced to techno music until sunrise... or so the hazy rumours of that fabled night at London's Fabric nightclub go.
Four months after they became a viral sensation, Władysław Nykiel, 82, and his wife Stanisława Zapaśnik, 79, have joined a campaign to save the club.
Fabric's licence was suspended last month following the drug-related deaths of two 18-year-olds.
More than 100,000 people have now signed a petition to reopen the iconic nightspot.
According to the Evening Standard, that list includes top DJs and record labels - and now the two Polish ravers have added their names.
Promoter Jacbob Husley, who featured in the famous photo with the couple back in May, posted a new image of Władysław on Facebook on Friday night, explaining that they'd joined the #savefabric campaign.
The lovely Polish septuagenarian ravers, who recently made headlines around the world when they came and partied at WetYourSelf at fabriclondon until 5am in the morning have just sent me this lovely picture in support of the #savefabric #savelondonnightlife campagn.
Władysław's wife is away at the moment but will apparently also be sending a picture in support :-)
I hope everyone who was touched or inspired by their story and shared it then will do so again, and sign our petition here.
