Reviving an old thread about an even older song...

I've been listening to 7 recordings of "Spanish Fandango/Flangdang", all instrumentals, by 6 different guitarists:
- Mississippi John Hurt (2 live versions -- one on Memorial Anthology, the other on Live)
- Elizabeth Cotten (on Freight Train and Other North Carolina Folk Songs)
- Mance Lipscomb (on You Got To Reap What You Sow)
- Etta Baker (on One Dime Blues)
- John Dilleshaw's 1929 recording
- Steve James's version, which is based on Frank Hutchison's 1927 recording

It seems like there are 2 different songs at play here:
1) The way that Libba, Mance, Etta Baker and Frank Hutchison play it sounds pretty much the way John Miller teaches it on his Guitar of Elizabeth Cotten -- although, of course, each guitarist adds their flavor to the song.
2) The versions by MJH & Dilleshaw sound somewhat like each other's, and completely different from the other 4.

In addition, Steve James writes this about "Spanish Fandango" in his Roots and Blues Fingerstyle Guitar book:

"Derived from the influential guitar music of 18th century Spain, this waltz was quite popular with American guitarists of the 1800s, and numerous arrangements were published. Here are the first two parts of Henry Worral's transcription, based on an 1860 version by J. and L. Peters. 'Spanish Fandango' is one of the true parent pieces in American guitar music, and many recordings exist. (Some, like those of John Hurt and John 'Seven-Foot Dilly' Dilleshaw, bear only a tangential resemblance to the one here)."

Tangential, to say the least -- it seems like Hurt & Dilleshaw have a completely different song in mind.

Any thoughts on this? Are MJH & Dilleshaw really playing really playing "Spanish Fangdango", or a different song entirely?
