³ÉÈË¿ìÊÖ

It's a very special theme on Strictly this week - celebrating 100 years of the ³ÉÈË¿ìÊÖ!

The dancing pairs will take to the floor to the themes of Doctor Who, Blue Peter, The Apprentice and lots more tunes made famous in ³ÉÈË¿ìÊÖ programmes.

The big opener for the night - danced by the professionals and judges - will see famous ³ÉÈË¿ìÊÖ shows taken over by Strictly fever!

You can find out all the theme tunes and songs, along with the chosen dances, below.

There are 12 pairs left in the competition - here's what they all will be dancing to on Saturday...

Former Blue Peter presenter Helen Skelton will get to dance a Charleston to her own theme tune!

It was written by composer Mike Oldfield especially for the show.

Ellie and Nikita get to dance to a theme tune that is already a piece of dance music. The Apprentice theme comes from a ballet of Romeo and Juliet.

The pair will be dancing a paso doble - which is a pretty fast-paced routine!

Grange Hill was one of the most popular ³ÉÈË¿ìÊÖ children's shows - it started back in 1978 and was set in a school in north London.

The pair will be celebrating ³ÉÈË¿ìÊÖ Children's and dancing a routine of their own choice to the theme tune.

James and Amy will dance a foxtrot routine to the theme tune of the ³ÉÈË¿ìÊÖ's most popular soap opera - which James has starred in since 2014!

EastEnders started in 1985, and it's set in the East End of London - there's been 34 series since it first aired.

Tyler and Dianne hope to put together an out-of-this-world performance to this famous theme tune - from one of the ³ÉÈË¿ìÊÖ's most famous TV dramas!

They will be dancing a tango - hopefully with no Daleks or Cybermen on the dancefloor!

Strictly has chosen this song by Imagine Dragons for celebrating ³ÉÈË¿ìÊÖ Nature - which includes ³ÉÈË¿ìÊÖ Earth, Planet Earth, and all shows about wonderful wildlife around the planet! The pair will dance a quickstep.

Casualty is a ³ÉÈË¿ìÊÖ drama set in a hospital. Ellie and Johannes will be dancing a Tango to its theme tune!

Jayde's dance will be celebrating all things ³ÉÈË¿ìÊÖ Comedy by dancing to comedian Victoria Wood's The Ballad of Barry and Freda.

You might be wondering how ABBA ended up on the line-up - it's all because of Eurovision! ABBA won Eurovision in 1974, when the competition was hosted by the UK in Brighton.

Next year the ³ÉÈË¿ìÊÖ will be broadcasting Eurovision from Liverpool - which was recently chosen to host the contest.

Fleur and Vito will be dancing a jive to Waterloo.

Kym and Graziano will be dancing to this song from the 70s to remember the ³ÉÈË¿ìÊÖ's dance show before Strictly - which was called "Come Dancing".

The pair will be doing a quickstep - a ballroom classic!

Grandstand was one of the ³ÉÈË¿ìÊÖ's longest-running sports shows. It's not been on since 2007 - but it started back in 1958.

Tony used to play for Arsenal and England's football teams - so he should be familiar with the song! They'll be dancing the Cha Cha.

Line of Duty is a ³ÉÈË¿ìÊÖ police drama that has been very popular with adults - Will Mellor starred in the show back in 2016!

The pair will dance a special Viennese waltz to the theme tune.

The special Strictly show is on Saturday at 6.40pm on ³ÉÈË¿ìÊÖ One and ³ÉÈË¿ìÊÖ iPlayer.
