Bally Hell! I Never Realised that it Had a Name
It turns out that the way Melbournian ravers dance is somewhat unique. The Melbourne Shuffle, Wikipedia Article ("this minimised people getting Kung fu'ed whilst dancing"), Youtube Video and Documentary DVD.
I wonder if they have a name for the dance I 'performed' at raves .. probably 'Melbourne Corpse Rolling Down a Hill' or 'Melbourne Skewered Animal Rolls Around in Agony'.
