The series continued the technique of using musical montage or "songtage" segments in each episode, originally introduced by McHale as a means of modernising the programme [REF].
On 13 April 2010, Holby City reached its 500th episode with "Bette Davis Eyes", in which Jac (Rosie Marcel) offers to donate a kidney to her mother, who abandoned her as a child, and Chrissie (Tina Hobley) gives birth to a son [REF].
