True karaoke fans know the difficulty of pulling off dairy-free renditions of Sinatra classics — which makes this version of "Summer Wind" sung by New York City subway construction worker Gary Russo streetside on his lunch hour all the more impressive.

Caught outside the Second Avenue line construction in Manhattan, the hard hats apparently stage a free concert to break up the monotony of construction noises with selections from the Johnny Mercer songbook. To those of us who hear music dying every time people open wide on "American Idol," we'd say Gary Russo deserves a bigger audience than a few traffic barrels and hurricane fences.
