Hello there. New to Mudcat so bear with ..

I'm doing some research for a BBC drama (ghost story!) and need a bit of information and hoping someone can help me.

1. Is the version of Scarborough Fair collected by Sharp in July 1913 from Richard Hutton of Goathland the earliest version of the song?

2. Are there any accounts of the meeting between Sharp and Hutton, or in general of Sharp's visit to Yorkshire

3. I'm guessing there will be several versions of the song; does anyone know how many and where they were collected from?

4. I understand SF is a descendant of a ballad called The Elphin Knight of which there is a MS dating from the 17th century. Does anyone know where that MS was collected and where it might be now?

5. Where might I get hold of a version called Whittingham Fair? Words and or music?

Many thanks in anticipation
