From today you’re able to purchase the single, Smile, from singer songwriter Katherine Crowe to help her reach her goal of a Christmas number one.
She recorded a version of the song, made famous by Charlie Chaplin, at the Abbey Road Studios earlier this month, accompanied by the London Metropolitan Orchestra.
There's already been a swell of support for the campaign with thousands of people vowing to visit iTunes to make the purchase today.
Some of the money raised will be going towards helping to develop new treatments for cancer - as Katherine has a terminal form of the disease.
She told us why she chose this specific song to cover:
