Hello Sitonmy
my favourite dances are Argentinian Tango (the real intense thing, not the Victor Sylvester version), and what is called Swing or Hustle, depending on land and dance school (what you'd dance to some Brian Ferry, like his 'The 39 Steps').
I'd like to have a go at Mambo or Salsa too, though the music isn't always my taste, and I know I'd have a partner problem because I have one now, especially for Swing. I can't understand why so many women over 30 prefer line-dancing, with its horrid music. Even if they don't want to hustle, they could be doing Morris instead, at least that's fun!
