The British television series Dragons' Den uses T. Rex's song “Get It On” as its opening theme.
“Get It On” is one of the best-known recordings by the English glam-rock band T. Rex. The song was written by Marc Bolan and became a major success in the early 1970s, giving the programme an immediately recognisable rock opening.
T. Rex had several famous songs, including “Children of the Revolution,” “20th Century Boy” and “Ride a White Swan.” Those titles are therefore plausible mix-ups, but they are not the Dragons' Den opening theme.
The use of “Get It On” helps give the programme a confident, energetic identity before the entrepreneurs begin their presentations. The music is a branding element of the British television version rather than a description of the investment process itself.
