Among many, just saying the phrase "This one goes to 11" brings a knowing nod and a smile. The famous scene in 1984's cult classic "This Is Spinal Tap" where British prog rocker Nigel Tufnel (Christopher Guest) tells documentarian Marty DiBergi that he's had his amps modified to go "one louder" than 10 is used as shorthand to describe absurd behavior by empty-headed musicians.
Now it's a holiday.
Another member of the Tap faithful, Adam Gimbel, will have armadillos in his trousers as he performs with his Spinal Tap tribute band Twelve at 11:11pm that night. Gimbel has created a separate "worldwide party directory" for Nigel Tufnel Day that lists over 40 celebrations across the globe.
Though the band has reunited periodically over the years (and as parallel mock band The Folksmen), the only official partying by the actual group on the holiday will be when Nigel Tufnel and Derek Smalls (Guest and Harry Shearer) do a special Skype chat before a screening of "This is Spinal Tap" at Brooklyn's hip BAM movie theater.
All this is pretty amazing for a film that barely made a whimper at the box office when it first came out, but has continued to spread its legacy as the most beloved mockumentary of all-time and a favorite among musicians including The Edge, Eddie Van Halen and Tom Waits.
"There is a certain beauty to the perfect stupidity of Spinal Tap," said Fennelly. "So much of what happens in the movie is true that many musicians feel pangs while watching it because basically your whole career is mocked."
