 The song incorporates a drone-effect on the electric guitar, reminiscent of the Indian sitar and tambura.Although writer Jonathan Bellman sees it as the first Western rock song to integrate Indian raga sounds (released four months before the Beatles' "Norwegian Wood (This Bird Has Flown)").Davies biographer Johnny Rogan notes that a preceding single release ("Heart Full of Soul" by the Yardbirds) was "pre-empting Davies's innovative use of Indian music".
