For those of you who love mash-ups but hate technology, this video is for you!

A new project on YouTube, Videos Recorded Live, produced a live, one-shot mash-up of RJD2′s 'A Beautiful Mine' (aka the 'Mad Men's' theme song) and 'Nature Boy' by Nat King Cole. There are no cuts, over-dubs, lip-syncing or auto-tuning. It is simply a big band and Brian Williams' daughter Allison Williams.

The composer of 'Mad Men's' theme RJD2 is a predominant electronica artist, a genre that Don Draper would no doubt furrow his strong brow at.

However, this mash-up (another term Draper would hate) turns the song into a piece completely appropriate for the crowd at Sterling Draper Cooper Price. Williams timeless voice, which has won her scores of YouTube fans with her covers of 'Tik Tok' by Ke$ha and 'Hallelujah' by Leonard Cohen, makes her a perfect candidate for a smoky club singer who Draper seduces next season.
