Lindy Hopping today seems to be mostly acrobatic tricks.  The kids 
don't stop to learn the fundamentals first---they just start throwing 
each other around. To be done right, the Lindy is mostly footwork, and 
now there is no real footwork anymore.  And they can't do it 
fast, they have to dance half time.
  Shorty George Snowden.

"There is no song that is too fast to dance too. There may be a song which, at
the moment, you are not skilled enought to keep up with, but that is another
metter entirely. So if something is too fast it looks like you need some
practice, Jim."
