London organisers say the closing ceremony of the 2012 Olympics will be themed ‘A Symphony of British Music’ - a hit-packed journey ranging from classical composer Edward Elgar to chart-topping singer-songwriter Adele.

Artistic director Kim Gavin says the August 12 show will be an "elegant mashup of British music" packed with recognizable songs arranged symphonically.

The London Symphony Orchestra will provide musical backing.

Gavin, who has overseen tours for the band Take That and directed the 2007 Princess Diana memorial concert, says the closing ceremony will be "the biggest after-show party – the show being the sport".

The creative team revealed some details of the closing ceremony Thursday, but are keeping the names of many artists involved under wraps. The games start July 27.
