Thanks! In many cases the people teaching it are direct from the island. However I haven't paid that much attention to what they are doing so I may be mistaken about the use of the backwards and forwards step. (I'll have to do further investigation and report back.) I will say that here in Europe the authenticity angle is a major part of the advertising/propaganda campaign. Also, I think Miami style salsa/casino has had little or more likely zero impact in Europe. (I've even heard of a Cuban salsa instructor stating that Cubans from Miami are not real Cubans.) Whilst we're both here, I have a question re. the history of casino: the other day I found a brief clip of casino from (I think) '81, which predates the Cuban TV show Para bailar casino. Do you know of any footage of casino prior to this? I know there is quite a lot of vintage footage of Cuban dance, but afaik it's all son, rumba, cha cha cha etc. Never casino.
