This will be old news to many of our fine members here, but it was new to me! In '68, Jazz musician Bill Plummer did this kind of "Jazz/Pop/Raga" album, and Crosby's tune is included.
Alot of Sitar, at least one Tamboura, and the melody is played out on Marimba. If anyone (Especially Byrds "Completists") would like it, here you go:

Album also features kind of nice cover of Bacharach/David's "The Look Of Love", which I think was inspired by Ursella Andress???
Anyway, enjoy, or not.
