"Mad Men" star Jessica Pare's rendition of Gillian Hills' 1960s tune "Zou Bisou Bisou" has shot to the top of iTunes' download list after the actress performed the French pop tune on the season premiere of the hit drama on Sunday.
 
Pare performed the tune in character as Megan Draper at a birthday party and her version of the song, which Sophia Loren performed in "The Millionairess," was one of the most in-demand downloads on Monday.
 
A limited edition seven-inch single of the recording is available to fans of the show via the Mad Men website.
