in 2001 (beginning with Storm Warning), they approached composer David Arnold, who produced a new arrangement of the Doctor Who theme for the Eighth Doctor. The Arnold arrangement was used for every Eighth Doctor audio play until 2008's Dead London. They proceeded to use this theme arrangement again from 2012's Dark Eyes onward. In 2005, the television series was revived. Murray Gold's theme arrangement featured samples from the 1963 original with further elements added: an orchestral sound of low horns, strings and percussion and part of the Dalek ray-gun and TARDIS materialisation sound effects. Rapidly rising and falling strings were added to create a counter-melody alongside the main motif. The sting once again served as the lead-in to the theme, but Gold omitted the "middle eight" from both the opening and closing credits. Gold has said that his interpretation was driven by the title visual sequence he was given to work around. Gold created a variation on his arrangement for the closing credits of "The Christmas Invasion", which was performed by the BBC National Orchestra of Wales. Unlike his arrangement for the 2005 series, this version restored the "middle eight"; it was also used for the closing credits of the 2006 and 2007 series. A soundtrack of Gold's incidental music for the new series was released by Silva Screen Records on 4 December 2006. Included on the album are two versions of the theme: the 44-second opening version, as arranged by Gold, and a longer arrangement that includes the middle eight. Often erroneously cited as being the same as the end credits version, this second version is in fact a new arrangement and recording. Gold also created another new arrangement of the theme which was performed by the BBC National Orchestra of Wales during a special televised concert, Doctor Who: A Celebration which was broadcast in November 2006 as part of the annual Children in Need appeal. A second soundtrack with music from the third series plus the 2007 Christmas special, Voyage of the Damned, was released on 5 November 2007. In November 2007, following the BBC's announcement that it was requiring all series to implement a shorter closing credits sequence, Murray Gold produced a third version featuring additional drums, piano and bass guitar and a variation of the string counter-melody while retaining the original Derbyshire electronic melody line, used from the Christmas 2007 episode. The 2008 series featured a
