I play some lap slide, which means no actual cords, with my harmonica on a rack and a tamborine under a foot. I can fake it make it work. Ah.....three string cigar box geetar.
Video is s little dark but so isn't Neil at times. Either he wanted to improvise on the song or he just got lost but it seems like he inadvertently went for the harmonica a few times. "Heart of Gold" was probably his biggest hit w/ harmonica but this song is one of my favorites.
