The original Panorama titles showed the London skyline
The current theme tune is called Aujourd'hui C'est Toi and was composed by Francis Lai in 1969.
The latest version was mixed by David Lowe in 2005 but there were two earlier versions of it.
Before that, in the late 1950s and 60s, the programme opened to a piece of music called Opening and Endings written by Robert Farnon.
The original music on November 11 1953 was an extract from Jean Silbelius' Pelleas and Melisande.
In 2001 a spin-off version of Aujourd'hui C'est Toi was secretly made by two BBC music librarians, Paul Jackson and Adam Dineen. Their remix has a Dallas-sounding opening and dance beat.
They made it after hearing a rumour that Paul Hardcastle was to be invited to remix the music. They played their version to the Panorama team who were so impressed the remix was broadcast in July 2001 in a programme about Jeffrey Archer.
The Panorama theme tune has never been commercially released.
