Here in Australia RnR does exist independently of EC/WC, swing and jive. My partner and I have only learnt jive so far, but RnR and swing are on the cards for later.

Just thought I'd add that.

Lindy Hop is the only way to go.

Check out this video to see an example of Lindy Hop to Rock N' Roll:

Back in the fifties....late fifties I think...we danced what we called "Rock and Roll". It may actually have been ECS or perhaps Jive. We thought of "swing" as the Lindy only. I remember the dance starting out like ECS. I don't think we did it correctly. I'm not saying there isn't a specific dance correctly called Rock and Roll, just that we used that name for the dance we did, whether it was correctly named or not.

Actually , there are clubs dotted around the planet, that will adamantly state-- of course there is .

Your reference was partially correct, but rambled to include 3 separate types of " swing "( generic term.)

Lindy is a dance unto its self as is jive. Rock and roll could be identified
as a single time swing, danced primarily to fifties music . They are all related , and many of the variations appear in all 3 forms.

Single time swing would be the easiest dance to learn. Up tempo 60's music is a form of swing and some ballroom DJs, play a lot of 60's music. Many of the 60's hits are remakes of 40's swing music. Once you learn single time, learning East coast would be a good next choice. Since you can use same manuevers, replacing the 2 slows with 2 triple steps.

A minority opinion is that 60's music is the best swing music. I don't agree with that, but still think it is good swing music and fun to dance to.
