Makes sense to me.
I play in a Celtic group, lived in Ireland as a kid, etc.. I found playing my fretless bass along with ragas to be pretty natural. The western 12 notes to the octave is merely a convention, not an absolute.
Davy Graham broke open interest in raga in fingerstyle guitar with 1962’s “She moves through the Fair”, better known to many as “White Summer” (Jimmy Page recorded it while still in the Yardbirds, and re-recorded it during the Zep years; “Black Mountain Side” is a ripoff of an old folk tune “Black Waterside”). SMTTF is considered a traditional (public domain) song, but unlike a lot of stuff in that category, its authors are known.
