Two different versions of the same song are at Numbers 1 and 2 in the UK charts during Christmas week for only the second time ever.

X Factor winner Alexandra Burke's cover of Leonard Cohen's 'Hallelujah' shot straight to the top of the charts, and also became the fastest-selling single by a female artist - with over half a million sales in one week alone.

A campaign by X Factor dissenters also meant that Jeff Buckley's version of the song - taken from his album 'Grace' - is at number two, while the original, by Cohen himself, is at number thirty-six.

In Ireland, Burke also topped the charts after a week of sales, but Buckley's cover only reached number nine. The Irish Christmas chart will be revealed tomorrow.

It's good news for Cohen, however, who was allegedly left with just $150,000 to his name after his ex-manager Kelley Lynch mishandled $5 million of his retirement fund and the publishing rights to his songs. Although he successfully brought a civil case against her and was awarded $9 million in 2006, it's believed that he will never receive that money - as Lynch has reportedly ignored issued subpoenas.
