Gime, bandoneon, tu tango gris

The title means "Moan, accordion, your grey tango" and it's a verse from a wonderful tango, "Nostalgias" [link] (I couldn't find the version I first heard, it's better imo, but this one's nice too). I thought it would fit the black & white drawing and my username .
Unfortunately my scanner isn't a very good one...I softened the image but it still looks odd.
