not sure if pb100191 is being sarky? (This question is asked daily on here)
But it is a version of LIFE ON MARS by DAVID BOWIE. It is in sung in the style of Seu Jorge who sang it in Portuguese. Which you can listen to on the link below

At present though there is no information as to who the people are in the advert, and who has been credited with the version in the advert
Hopefully 3 mobile will have been deluged with the question "who is that singing" and will release the info
