Barlow: Sharon having a positive effect on everybody

Gary Barlow enjoys 'The X Factor' more now that Sharon Osbourne is a judge again.
The 'Talk' host returned to the judging panel of the show this series, replacing Tulisa Contostavlos, and the Take That frontman says she has had a "positive" impact on the panel - which also includes Louis Walsh and Nicole Scherzinger - and he is having a lot more fun this year.
