The Beatles hit 'Hey Jude' has emerged as fans' favourite after the Liverpool band's entire back catalogue was released on iTunes earlier this week.

The Liverpool fab four's music was finally made available to buy on iTunes after years of negotiations.

From the first week's sales the McCartney track 'Hey Jude' is the biggest selling Beatles song, reports The Guardian.

Bookies William Hill put the odds of a complete top-10 made up of Beatles songs at 10/1 before the end of 2011.

Meanwhile, Yoko Ono showed her support to this year's X Factor contestants following Saturday's Beatles tribute night.
