This is a guy named Ralph Giese performing on the Detroit 'Kelly & Company' talk show in the early eighties. The song is 'Georgia on my Mind', which is famous for being the official song of the American state of the same name. Ray Charles recorded a cover, as did Billie Holiday, but Mr. Giese relays it with a particular emotional brunt that yanks furiously upon your heart-strings. As you can probably infer from the post title he whistles the whole song while being backed by a suitably tender instrumental. But when I say whistling this isn't the tuneless pursing of lips you see everyday. This is something all together more. Its brilliant, so stream it up above and prepare to be amazed and inspired and somewhat entranced!
