I repeat - they were great, they should have been BIG!
They formed in Barnsley, England around 1980 and through their short spanned early life (as they' ve reformed lately), they bore a strange symbol, that of a crown of thorns.
The crown of thorns was worn by Jesus on his final moments and in christian iconography it is often represented with the three nails of the cross.
Danse Society used it from 1982 to 1985. The members of the band who reformed around 2010 decided apparently that this symbol represents them so it is again to be seen in their current websites, shows and releases.
Their first release to bear it was the 12" of "Somewhere" in 1983.
It was also the main motif on the cover of their splendid LP "Heaven is Waiting in 1984.
I recently discovered an a christian children's colorbook with this very similar depiction of the crown!
See how it's used today by the band on their website: http://www.thedansesociety.co.uk/
