PAUL AND RONNIE WOOD ARE MOBBED BY FANS AFTER THEY PERFORM ON STAGE WITH JAMES

The evening was supposed to be about James McCartney and his new concert tour.

But, the musician was overshadowed when his father and sister Paul and Stella McCartney arrived to show their support on Wednesday night.

As if the famous family members weren't enough of a distraction, Rolling Stone Ronnie Wood also turned up to steal the spotlight.

James, 35, played at the Ambassadors Theatre to preview his upcoming show which he is set to take to America for a 47-date tour later this year.

He performed tracks off his debut album Me as he entertained the crowds for the evening.

However, the musician was left in the shade as two of the most iconic rockers turned up to support him.

Paul watched on from the wings as his only son took to the stage, even though many fans were there in the hope of catching a glimpse of the former Beatle.

The situation was exactly the same for Ronnie, who had accompanied James on his guitar. Paul also joined in the fun on stage by playing piano during the concert.

Once the show was over both Ronnie and Macca left the theatre separately as they were surrounded by fans clamouring for photographs and autographs.

The superstars still clearly have enough star power to cause commotion and pandemonium ensued when Ronnie left the venue.

At one point Paul looked slightly scared as he couldn't find his car due to all the commotion - also losing his wife Nancy Shevell in the crowds.

But the pair eventually managed to find each other, looking relieved as they settled back in their car.

An onlooker said that one fan kept shouting that he'd come all the way from Liverpool to see Paul and wanted the rock star's autograph.

Ronnie's wife Sally Humphreys, who is a theatre producer, had put together the event and encouraged her husband to perform.

He tweeted earlier this week: 'Don't forget I'm going to be playing at the James McCartney gig this Wednesday.'

Also in attendance was British designer Stella who covered up in a long grey pinstripe coat as she watched her brother.

X Factor supremo Simon Cowell was also seen leaving the theatre in his standard black jumper and jeans combination.
