I have to agree with lilfin, it is based around a Bert Jansch song. It comes from the sitar-like D-modal tuning (DADGAD) which Jimmy uses of a few yardbirds & zep songs, White Summer (Yardbirds 'Little Games', 1967), Midnight Moonlight (Zep left-over later called Swan Song) and most famously Kashmir. He was taught the tuning in 1966 by Al Stewart who taught him to play the Jansch song Black Waterside which it bears definite similarities to. I love this song.
