I've recently been looking at this lovely traditional song - both Martin Carthy and Pentangles arrangements. Its fascinating seeing how a song can be interpreted in different ways; the subtle differences in the melody, harmony and rhythm of the song. Carthy's version puts gives the whole song a 12/8 feel with a relatively simple fingerpicking pattern whereas John Renbourns guitar part is in 4/4 and uses a lot more of an alternating bass / american folk rhythm.
