Awesome “Mad Men” Theme Song Mash-up
It’s the Mad Men theme (known officially as “A Beautiful Mine” [sic] by RJD2) combined with “Nature Boy” from Nat King Cole. This was shot in just one take (although this was take 29 of the day).
Yes, this clip was posted almost two years ago. But the Internet is a big place, innit? Thanks to Peter for the link.
The vocalist is Allison Williams, who plays Marnie on HBO's Girls.
