If you want to feel ancient today, boy, have we got the story for you.
Its been 15 years since School Of Rock was in cinemas, and now one of its child stars is old enough to drink with the man who played his teacher.
Time is a serious trip.
Jack Black, aka Dewey Finn/Mr Scheebly, has reunited with Kevin Clark, who played drummer Freddy Spazzy McGee Jones in the 2003 comedy, and its a big old dose of nostalgia.
Kevin, now 29, has his own band called Dreadwolf, and Jack and his Tenacious D bandmate Kyle went along to see the group in Chicago.
And the former castmates couldnt let the occasion go by without a social media snap.
A picture of Jack and Jyle cosying up to Kevin and his bandmate was posted to the Dreadwolf Instagram account and Facebook page, with Black, 49, wearing a Dreadwolf t-shirt.
Quite the endorsement.
Kevin captioned the pic: Kinda a must here, but its not every day you get to see Jack Black wearing your t shirt.
Freddy – we mean, Kevin – looks rather different nowadays (the passage of time does that), swapping his spiky hair for long locks and facial hair.
The former child star has been drumming since he was three years old, and appeared as the drummer in Mr Scheeblys class band.
School Of Rock follows Black as a wannabe rock star who pretends to be his teacher friend to make some much-needed cash – but soon turns his class of precocious students into a rock group to enter a Battle Of The Bands contest.
The movie also starred Sarah Silverman, who just received a star on the Hollywood Walk Of Fame, Joan Cusack, and Miranda Cosgrove, who went on to front iCarly and launch a pop career.
School Of Rock has now crossed to Broadway and the West End for a critically acclaimed stage adaptation.
