Hello kind forum members,

I'm trying to transcribe the acoustic demo of Sandy Denny's "By The Time It Gets Dark" off of the "I've Always Kept A Unicorn" compilation, but I'm having a hard time with the tuning.

Does anyone know definitively if this is in DADGAD? Or is this in a sort of open D with an F# at the top? (Side note: What sort of D tuning with a high F# are commonly used by folk guitarists?) Sometimes I hear a strummed D5 chord that you'd play with a middle finger on the second fret in DADGAD, but there's also some high A, G, and F# notes throughout that make me think it's not in DADGAD.

There's a guy on YouTube that's playing an arrangement in DADGAD, but although it sounds similar, he's not hitting those high notes. There's also Maartin Allcock, who sold a 1000-copy print run of "The Sandy Denny Complete Songbook" back 2005. Anybody have access to this and can tell me the tuning used in the version there?

I usually play bluegrass and Bill Frisell-esque americana jazz, but I'm new to folk with open tunings. I've played through some Nick Drake, Bert Jansch, and Martin Simpson TABs so far, but that's really it. Any help would be appreciated. Thanks for your time and expertise!
