YOU would have to be living in a cave not to know that Bart Simpson and The Smurfs are both famous cartoon characters.
But you might not realise that they are also both dance moves – both of which are taught at a Crawley dance studio which is going from "strength to strength".
Since street dance classes were launched at Sway Dance Studio two years ago, the number of children taking part has more than quadrupled, and for the first time four-year-olds joined this week.
The studio is based at The Hawth and opened when Parkwood Leisure took over management of the facility from Crawley Borough Council.
Tutor Keira Whittaker has been so impressed with the talent in her home town that she is now looking to start a street dance crew to perform in competitions.
Miss Whittaker, from Southgate, who has a degree in street dance, said: "When we started the street dance classes we had less than 20 children but it has gone from strength to strength to strength.
"We now get more than 80 children and teenagers, both girls and boys, taking part each week.
"A lot of them have been sticking with it since we opened and you can see that they really enjoy it. There has been a rise at the start of this year as well where we have seen more people wanting to give it a go come along. For the first time we have opened the classes to four-year-olds as well due to demand."
Rather than simply setting out routines for the children, aged from four to 18, to memorise, Keira teaches them individual moves and encourages them to link them together to come up with their own routines.
The 36-year-old said: "I am the only qualified street dance teacher in Sussex and I encourage children to express themselves.
"I teach them the name of each individual dance move – including The Smurf, The Bart Simpson, The Shuffle and The Steve Martin.
"The children can then put these moves together themselves to create their own routines which they can show off in our 'freestyle circle'."
Keira, a professional dancer who has performed all over the world including in Portugal and Lapland, thinks the classes have helped to bring some of the children out of their shells.
She added: "You see the children grow in confidence.
"There was one boy who didn't even want to walk into the studio on his first visit but once I got him to buddy up with another dancer he found himself.
"His mum has said it is also helping his school work.
"He starred in our show last year and now cannot wait to get back on stage."
Street dance lessons are held each Monday in different age groups.
They begin at 4.15pm for four to seven-year-olds.
Then there is a class for eight to 12-year-olds at 5pm, followed by 13 to 18-year-olds being taught from 5.45pm.
Before the studio opened in October 2012, the space was used by the marketing team at the theatre.
Other classes at the studio include ballet, drama, singing and activities for children as young as one.
