"Do you want to meet someone famous?" 

 

This question from a teacher is answered by a boy, no more than seven, shouting after his mate with an enthusiasm that suggests he has discovered a tap dispensing free chocolate: "Haw, there's someone in the gym we have to see."
The two pals thus join a class of pupils, a clutch of aspiring coaches, a couple of media types and Judy Murray as she sets out to bring tennis to another part of the world, in this case St Thomas Primary School in Riddrie, Glasgow.
Judy Murray, star and judges' target of Strictly Come Dancing, mother of not one but two Wimbledon champions, and queen of the Twitterati with 135,000 followers, is doing her day job.
The habitué of glitzy ballroom and grand slam final player's box is also White Van Woman.
"I have always been a teacher," says Murray who is taking her Set 4 Sport, Set 4 Tennis and Set 4 Coaching classes around schools in Scotland with her helpers and equipment packed into a van branded with the name of her sponsors RBS.
It may not be glamorous but it is what Murray has always done and what, one suspects, she will always do. There is an urgency, though, about her efforts.
"The clock is ticking," she says as the window of opportunity afforded by the success of her sons slides ever nearer to closing. "I am passionate about getting kids active. I am passionate about getting kids into tennis. We have had a huge opportunity for several years to piggy back on the success of Andy and Jamie.
"I have played tennis all my life and I never anticipated we would have this opportunity. The time to invest is now. We need a much bigger and stronger workforce delivering tennis across the country."
Andy, of course, is the Wimbledon champion, the US Open winner, the Olympic gold medallist. Jamie is the Wimbledon champion in mixed doubles and a multiple winner of doubles titles on the ATP tour. Andy is 27 and Jamie is 29.
"This is an incredibly demanding sport on the body and who knows how long Andy has at the top? It is also a highly pressurised environment for him at the top of an individual sport, especially one when you have the microscope on you almost every day. I do not know how long he goes on for but I do know the time is now to make sure we tap into the excitement caused by his success."
The commotion in the gym testifies to this feeling that someone important is in the room and something thrilling is about to occur. The coaches are taken through the Murray workbook where games are played that improve co-ordination, agility and balance among the youngsters but also show the young coaches how to mentor and organise a training session.
This where Murray comes alive, encouraging both pupils and coaches. This is the White Van Woman Roadshow that has already travelled across Cumbernauld, Falkirk and East Lothian and after Riddrie and the South Side of Glasgow, heads for Raploch in Stirling and to Dunblane. Murray is hoping for a trek into the Highlands soon.
"We want to go to areas where people want to have us but where there is no history of tennis or even facilities," she says, pointing out that the nearest courts to the East End school she is standing in are private ones at Stepps and Mount Vernon.
Murray seeks to increase the appetite for tennis but also wants that to be sated though building more courts. This may take local authority and government intervention but she is determined to take the van on a singular journey.
"I have always been one of those people who believes if you want to make something happen then do it yourself, do not wait for somebody else to do it. It all revolves around people. We have to give them support, encouragement and resources," she says.
She also has revised her plans to build a tennis and golf centre near Dunblane, scaling it back after objections. The number of houses to be built will be reduced and the golf course will be limited to six holes but there will be indoor and outdoor courts. "We want it as a base so we can take tennis into the community but always have somewhere to come back to so that we can improve players and coaches." But on a chilly Monday it is a gym in Riddrie where the pupils politely asked for photographs and giant tennis balls are signed. The tennis teacher is being treated as a celebrity.
"Some of them may know me off the telly but all of them know Andy and most of them know Jamie," says Murray. "I really enjoyed doing Strictly and I am so glad that I did it. It was completely out of my comfort zone. It was a challenge learning something new at my age and putting yourself out there," says the 55-year-old. "I made a lot of new friends, I kind of learned to dance, though not very well, and it was a chance to enter a whole new world, the chance to step away from tennis for a few months. I was also around around people who did not talk about tennis."
This interlude, though, ended abruptly. "We got bumped off Strictly on the Saturday in Blackpool and by the Thursday I was in East Lothian in my van." With that, she says her goodbyes and heads into the aforementioned van for a trip to the Gorbals. Ah, the joys of celebrity and the allure of the Murray tennis circuit.
