Primary school children were treated to a surprise performance from famous dance troupe Flawless.
The Parent Teacher Association at George Tomlinson Primary School in Leytonstone organised the show on Tuesday.
The troupe competed in the third series of Britain's Got Talent in 2009, making the final alongside fellow street dance troupe Diversity.
The PTA funded the visit for children in years three to six, with workshops for year four classes.
