The musicians at Postmodern Jukebox have delivered their latest throwback-style cover.

This time, it's "Someday" by The Strokes and singer Cristina Gatti gives the pop-friendly rock anthem a 1940s twist.

Sultry and slick, this Casablanca-style take is pretty different than Julian Casablancas and Co.'s original, but it's hopelessly catchy all the same.
