[Callers] rocks and dirt by Erik Weberg

The first couple times I danced this I copied it down, so I know that this was a version of the original.  I believe it was Carol Ormand who called the dance both times, but I'm not certain. Can anyone share their opinion on why the caller would have chosen to make the change in the dance?  orientation or flow?
