As most know, Tango is not a " Swing " dance, and it is nigh inpossible to put into writing all the characteristics that are vastly different from the other 3 .
Tango was NEVER taught in the Br. level many yrs back ( never made sense to me ) and yet, Len ( Scriv ) always felt it was the easiest dance to get someone travelling around the floor .
One other reason, the " style " of the dance , had frequently been the one with the most disagreement as to its execution .
