Tube strike and travel disruptions notwithstanding, impresario Cameron Mackintosh succeeded yesterday (3 October 2010) in putting on a spectacular finale to the 25th anniversary celebrations of Les Miserables: an epic birthday concert performed by a 500-strong company and watched by a 20,000-strong capacity audience at The O2 – and watched my many thousands more at cinema screens across the country (and, from today, around the world).

And our video partners at Reelkandi were there to capture all the glory and talk to the key players behind this momentous occasion....

The cast of The O2 company was led by Alfie Boe as Jean Valjean, Nick Jonas as Marius, Norm Lewis as Javert, Matt Lucas as Thenardier, Lea Salonga as Fantine, Jenny Galloway as Madame Thenardier, Katie Hall as Cosette, Ramin Karimloo as Enjolras and Samantha Barks as Eponine, joined by the casts of the West End production, the 25th anniversary production (which finished its homecoming season at the Barbican on Saturday) and members of the original 1985 London company.
