Following on from its recent charity-fundraising Teenage Cancer Trust concerts, spearheaded by The Who's Roger Daltrey and sold-out in many cases, London's iconic Royal Albert Hall continues to set aside its usual activities to throw open its doors to a worthy cause, once more.

The Sunflower Jam returns in 2012 for another star-studded line-up and exclusive collaborative appearances from some of the biggest names in British rock and classical circles. This year's concert will take place on Sunday 16th September and will be hosted by actor and master of ceremonies Jeremy Irons.

Featured musicians include Deep Purple's Jon Lord and Ian Paice, Whitesnake's Micky Moody, award-winning classical maverick Nigel Kennedy and vocalists Alfie Boe and Bruce Dickinson. Since the show is billed as a 'superjam', that's precisely what to expect - all of the artists performing separately and together throughout the show.

Jackie Paice, wife of Deep Purple's Ian set up the UCLH-based Sunflower Jam charity in 2006. Its aims are simple: "Sunflower Jam works tirelessly to raise money and awareness for holistic and integrated care for children, young people, adults and their families with a range of acute and chronic emotional, mental and physical conditions."

More names are due to be announced soon, but meanwhile you can purchase tickets for the show at various prices, the cheapest being £50 for a front circle seat and the most expensive weighing in at £130 for stalls.
