It's a normal enough drill; band ambles onto stage, plays for 90 minutes, and leaves.
But there the normality ends. For there is nothing normal about the block-boys.
Ordinary? Nah. Extraordinary? Now you are talking.
Look the Other Way - taken from 2013s Same Horse Different Jockey opus - trots along nicely, with the band mixing fluidity with the usual character and sublime playability.
It's a Sunday night opener to ease us into a set spanning the years - If I was With A Woman and Express Yourself follow in close succession, flooding the senses with a brilliant buzz of Blockhead-manship.
This isn't an outstanding performance either. With this lot, there's an expectation of perfect playability, and they always rise to the challenge.
Everyone gets equal billing on the stage, with time to put their point across musically.
"Settle into the back of your seats," invites Derek The Draw, man at the mic, introducing Inbetweenies.
"I usually have a costume change," he says, "So if you can look at your feet..." before switching his glasses. And wow, there is a certain specs appeal going on with the green lenses.
Hacking at the bass, Norman Watt-Roy is legendary (that word is bandied about far too much, but not this time) contortionist. Fret-fanatic and player fantastic, he is truly in a league of his own and you could cheerfully watch him all night.
Last time The Blockheads rolled through these parts, NWR was otherwise engaged, so tonight's return is a welcome one.
To Norman's left, guitarist John Turnbull is feeling the music, cutting the occasional shapes and letting loose the odd yodel. Turnbull and Watt-Roy share many an impromptu look, smile and hook tonight, clearly relishing each other's musical company.
If only all relationships remained so sweet after so many years, eh?
Further along, and ace saxophonist and clarinettist Gilad Atzmon is plumping up the package with terrific sax-appeal dribbling over the proceedings.
Keeping things in check at the back with his own rhythm sticks, John Roberts is on track and on time.
To his right, organ and synth are under the control of Mick Gallagher, with Chaz Jankel splitting his time between the keys and the guitar.
They play What A Waste and make a decades-old song sound like a newbie, and every bit as exciting today as it was the first time.
Wake up and Make Love With Me (with it's naughty naked nude and wriggling and gift for womankind) is followed by Billericay Dickie with duel vocals from Norm and Derek, before Sex and Drugs and Rock and Roll is let out to play.
"This got banned in the seventies, just like our new cover!" Norman declares.
See, they can still upset the censors.
I Wanna Be Straight follows, and a nod to the late Ian Dury and the still great Wilko Johnson comes before Sweet Gene Vincent.
The Blockheads in 2015 are saucy, mischievous, marvellous, naughty and essential.
They might be knocking on a bit now, as Micky Gallagher addresses ("We used to get to the gig and ask where the girls are...now we get in and ask where the toilets are,"), but blimey can they bring the party, and they still have a twinkle in their collective eye.
Hit Me With Your Rhythm Stick, Blockheads and Lullaby for Francies call time on the show with the capacity crowd on its feet showing appreciation.
The Blockheads are a bit like that longed-for annual summer holiday - you wait ages for it to come around, have great expectations, revel in the release, but all too soon it's over and you want to go again.
You'll not find a better all-inclusive package deal anywhere, we'll tell you that for nowt.
