Thats all well and good mate but the point has been mentioned before that there is NO particular Northern Soul Dance Style to teach.Every dancer has his or hers own style.These styles often are representative of the era and cubs they used to go to. For example the Wigan dancers have different moves to the later Stafford 1980s attendees.Then you get the Clifton Hall Cleethorpes people who mainly danced to uptempo 70s records and there in is a different style again.
If you go to an open minded across the board Northern night the records played will range from 100mph oldies,Mid tempo,R&B,70s,and modern.So you have to adapt your dancing if you want to stay on the floor a while.
The best you can do at a dance lesson is just learn to copy the basic steps of the particular instructor and the style they use,which may not be suited to you as an individual.
The key word here is INDIVIDUAL.just get up and develop your own style and along the way try to copy a few moves from people you admire and enjoy yourself.If you realy feel the music and let it grab you then you will be able to dance better than any instructor can show you
