the kids in track suits smash it..the other crew look like disco dancers that have just seen breakdance the film

cool video andy 

great shots of New York and stuff,

that crew with the headbands and fancy get up need to leave the breakdancing to the street kids

Some skills on show there...but you're right, one lot are street dancers the others are more 'kids from fame' lol

kids from fame..spot on si
