Jimmy Fallon channelled his inner Neil Young last night with an opening rendition of Iggy Azalea’s Charlii XCX-assisted “Fancy.” The reigning No.1 single got the folk treatment equipped with harmonica and acoustic arrangement. Immersed in his 70’s depiction of Neil Young, Fallon is joined by the real-life David Crosby, Stephen Stills and Graham Nash. Watch the Neil Young “Fancy” version above.
