In 1951 I was working on Long Island and had Tuesdays off. I went to Jones Beach regularly and watched Ed Durlacher start on stage with his orchestra and fill a floor in front of him with hundreds of folks off the board walk. He could make folks who knew nothing about dance have a great evening.

Do Si Do in New York's Grand Central Park to the calls of Ed Durlacher, who held reign as one of the most unique Square Dance Callers of all time.

His talk-through dance approach brought smiles to 10's of thousands of common folk introduced to Square Dancing over the over the years.

Every dance matches the music or maybe the music was chosen to match the dance  only Ed knows.  

From there the phrase of the music guides the dancers through each sequence as though it was a singing call.  

Durlacher and his Top Hands orchestra went into the recording studio of the Society of European Stage Authors and Composers in the 1950's and  recorded a library of Durlacher dances. These recordings were never released to the public. 

I obtained copies of these unknown recordings in order to preserve and digitize them for all to enjoy and download for posterity. 

The recording logs indicated the music used for each dance so we can see how detailed the selection was. 

You'll find these, issued as 10-12 dance sets, every few days at; 

They can be downloaded and saved. To my knowledge this will be the only source for these lost treasures.
