O2 and Nordoff-Robbins Music Therapy are letting you choose the final song to be performed at next Friday’s O2 Rockwell gig.

The 11 September show is set to feature some of music’s biggest and brightest talent including Razorlight, Tom Jones, Robert Plant, Joss Stone, Ronan Keating, Gaz Coombs & Danny Goffey (performing as Hot Rats), Gabriella Cilmi, Beverley Knight, Lulu, The Feeling’s Dan Gillespie Sells and David Gray. From today you can chose which of four classic songs you want to hear at O2 Rockwell, by simply clicking through on the right hand sidebar.

Will you chose The Beatles’ uplifting 1970 single ‘Let It Be’ , the Paul McCartney-penned anthem released after the legendary group split up? Or how about Free’s 1970 monster rock hit ‘Alright Now’ , a song with riffs so great it reached No. 1 in 20 countries?

If these two killer tracks can’t satisfy, how about The Beatles epic tribute to friendship ‘With A Little Help From My Friends’ ? Memorably sung by Ringo Starr in 1967, the song was also reinvented in terrific fashion by Joe Cocker a year later. The final choice is just as mouth-watering. Funk-pop classic ‘Kiss’ was originally released by Prince in 1986 but has also been memorably covered by O2 Rockwell star Tom Jones.

The two most popular choices will then be narrowed down to one by O2 customers voting via their phones live on the night, with the winning tune being performed by an incredible supergroup made up out of all the acts taking part in the event.

This will be the first time ever fans have been able to chose which song to hear at a gig using their phones, so make your vote count!
