JUDY Murray reckons her sons Andy and Jamie still aren't fully aware of the scale of the celebrity status which they have in Scotland. Tickets for tonight's 'Andy Murray Live' charity event at the SSE Hydro, with proceeds being split between Unicef and local Glasgow charity Young People's Futures, sold out within an hour of their release. While the World No 2 may be at less than full tilt on the night due to the thigh problem he sustained on Davis Cup duty on Sunday, the event - which will see him play a singles match against Grigor Dimitrov then partner his brother Jamie in a doubles match against Dimitrov and Tim Henman - offers a rare chance for a Scottish audience to see their heroes in action.

"I don't think they are [aware of how big they are]," said Judy. "Because they are simply not here enough. I think they know that they are very well thought of and very well supported but I don't think they are aware of the scale of it. Of course they have to live down south - because there is nowhere up here that has the right surfaces for them to train on, the right sparring partners and all the rest of it."

Scotland, of course, may see their favoured sons more frequently if Judy's proposed tennis development at the Park of Keir site near Bridge of Allan comes to fruition. Scottish ministers are due to make a final decision on that proposal within the next few months, but until then the focus is on building a work force to help grow the game in schools and clubs. "Of course in time we should be aiming to have some kind of national academy which is thriving but to have a national academy you need lots of kids, and the only way you get lots of kids through is if you have lots of coaches, lots of facilities and lots of kids coming into the game," said Murray. "We have a chance to do it and we are just not grasping it."

To that end, immediately prior to the main event on Tuesday night, Judy and Davis Cup captain Leon Smith will invite a lucky eight school kids onto the court at the Hydro in an attempt to replicate the experience which Andy and Jamie themselves had from some of the game's greats when they were children.

"I am doing a kids thing before it," said Judy. "It is entirely a fundraiser as you probably know, so I am doing all the corporate clinics during the day. The boys, Tim and Grigor are coming in at night but someone has to set it all up, to let them come in and do all their magic.

"From 6pm to 7pm we have four little boys and four little girls from the Bridge of Allan area and Leon and myself are going to go on court with them," she added. "What an experience for them, to be part of that, and be on the courts just when the crowds are coming in.

"I remember when the boys were small, they got a chance to play at something on Roehampton on the grass which had Marat Safin and Nicolas Lapentti and it was an exhibition type thing. They got a chance to play a set before they started, just to get the experience of doing that in front of a crowd, because you never get crowds in junior tennis, with some of the world's best players for inspiration. So we have got all that built in as well."
