Rock and Roll - Different styles? My partner and I are trying to learn rock and roll in order to compete in dancesport-allied events. We bought a DVD to try and learn (Kav Kavanagh) but the style he teaches ('authentic 50's jive and r+r') seems very different from the kind we have seen. The latter seems to be more of a kicking action whereas the former involves lots of turns. Are there different styles of rock and roll to learn - or is the version on the DVD just a basic introduction before progression to flicks and kicks? Thanks.
