Horn plays, players emerge, noise level cranked up.
The man with silver horn has arrived in the centre circle. The players in the tunnel can hear handclaps from the fans outside. It's a belter of an atmosphere under the lights.
Shohidur Rahman: Thought Ranieri might tinker a bit and go 4-2-3-1 with Mahrez in behind Vardy but he's sticking with the 4-4-2.
As usual, there's lots of flags being waved at the King Power, with children in the centre circle and along one touchline. In the stands, one chap who looks remarkably like Father Christmas is wearing a Leicester shirt. So that's why they're top of the league...

As a lifelong "Lesta" fan I wanted to say that wherever we finish this season I want the club to have an open top bus parade around the city. First, second, third, wherever we finish we've proved that money, egos and fickle fans are not what it's all about. Camaraderie, teamwork and solid hard work can get you a long way.

Big up to Nigel Pearson. Without him Leicester would be playing Rotherham tonight #itsafunnyoldgame

West Brom will make things very difficult, and I think they will see the job through. The Baggies are over their little blip now, and Saido Berahino looks like he has got his appetite back.
Prediction: 1-1
Right, have you got all of that? Up to speed? It's left to remind you how to get involved.
Two ways - text 81111, or tweet using the hashtag #bbcfootball., external Leicester to party the night away, or West Brom to spoil the fun?

"A late winning goal to bounce majestically back from a heart-breaking late defeat is yet another trait of a title-winning side. Those waiting for Leicester's bubble to burst will have to wait for yet another week, it seems.
"With 11 games to go, and while all those in the chasing pack have other significant distractions, Claudio Ranieri's team can focus solely on their remaining 'cup finals'.
"If it were a team more used to winning trophies, they would surely be even greater favourites.
"Visitors West Brom have proved to be stubborn opponents throughout this campaign and their weekend win has alleviated still further any lingering anxiety.
"Perhaps it will take yet another late goal to maintain the intrigue of one of the greatest footballing stories of recent times?"
Leicester v West Brom (19:45 GMT)
For the first time in living memory, Leicester make two changes, although neither is a surprise. Danny Simpson returns after suspension in place of Daniel Amartey at right-back, while the injured N'Golo Kante is replaced by Andy King in midfield.
Leicester XI: Schmeichel, Simpson, Huth, Morgan, Fuchs, Mahrez, Drinkwater, King, Albrighton, Okazaki, Vardy.
West Brom are forced into one change from the team that started the 3-2 win over Crystal Palace. Chris Brunt, who was injured in that game, is replaced by James Chester. Tony Pulis keeps two up front in the shape of Salomon Rondon and Saido Berahino.
Viva 4-4-2!
West Brom XI: Foster, Dawson, McAuley, Olsson, Chester, Sessegnon, Fletcher, Yacob, Gardner, Rondon, Berahino.
Because Pulis would have paid keen attention to Leicester's win over Norwich, one where the Foxes struggled to get past the Canaries.
Afforded possession, Leicester couldn't employ their trademark counter-attacks. There was no space behind the defence for Jamie Vardy, a crowded midfield not conducive to the trickery of Riyad Mahrez.
I wonder how the Baggies might set up tonight?
And that's where we are this evening, with Pulis taking his West Brom side to Leicester to meet the league leaders.
Yes, there's the intrigue of Leicester topping the Premier League and still being on a high from their late win over Norwich on Saturday.
But there's more to it than that, and not just because the Baggies have won their last two in the league and seem to have got Saido Berahino to behave himself.
You see, Tony Pulis knows a thing or two about ending a party - you can imagine he'd like nothing more than charging through the door, unplugging the speakers and pouring your booze down the drain.
He's got form for ending surprise title challenges too. Just ask Liverpool.
...a party that will last all the way to the end of the season, probably regardless of the outcome of their most unlikely of title bids.
Standing between the Foxes and possibly the most outrageous championship win of all time are 11 humps in the road, 11 obstacles for Claudio Ranieri's men to clear before achieving immortality.
The first is quite a big one...
Leicester City are having a party...
