I got a couple of breakdance singles last year at different boot sales, probably for about 25-50p each. The first is the soundtrack to the 80's film 'Breakdance - The Movie' (called Breakin' in the US). My friend had both Breakdance movies on video and I loved them. As far as I can remember, they revolved around saving the local youth club somehow through the power of breaking. No, really.
Anyway, here's the video to Ollie & Jerry's UK no.5 single There's No Stopping Us, which also reached no.9 in the US chart. Prepare for some toprocking, downrocking and power moves. Plus a lady in legwarmers, obviously.

The next was Break Machine's Street Dance. This peaked at no.3 in the UK in March '84 and no.6 in the US dance chart. This video is a tad quieter so you'll need to whack the sound up a bit more.

The squeak at the start of the film is my cat Ethel meowing. She loves this song too.
