I have watched this thread progress and now am annoyed enough to write and ask
'Why is that many of you can not / will not / do not wish to purchase a copy of the original publication for yourselves?'
In this case, the 'Dunsmuir Dances' collection is still in print and is available from TACBooks. It is also advertised on the San Francisco Branch website.
With the 'marvels of modern science' a copy could be ordered and despatched within a couple of days. Admittedly, the postal service may considerably add to the time before you actually receive the book.
To me, there is no need to plan to teach a dance without having the original instructions to hand, and, a crib is not the 'original' instructions!
The only time anyone should really need to request instructions from other members of this forum is after having ascertained that the original publication is out of print or that the deviser can not be contacted for a copy.
