It samples Peggy Lee's 1947 version of the 1936 song "Why Don't You Do Right?".

[1] Fraser McAlpine of BBC Chart Blog gave the song a mixed review stating: I'm detecting a theme here.

After the burlesque boom and all the Winehouse wannabes – and Wiley's reworking of that song by White Town that samples that other song from the olden days – here comes dance music's tribute to the era of jazz, swing and blues.

And when I say tribute, I mean taking an old tune and hitting it with a massive mallet until it cracks into a million pieces, then putting the bits back together with micro-robots and spraying it gold.

That is simply how dance music likes to pay tribute to things.
