91Èȱ¬

It's a very special theme on Strictly this week - celebrating 100 years of the 91Èȱ¬!

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 91Èȱ¬ programmes.

The big opener for the night - danced by the professionals and judges - will see famous 91Èȱ¬ 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 91Èȱ¬ children's shows - it started back in 1978 and was set in a school in north London.

The pair will be celebrating 91Èȱ¬ 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 91Èȱ¬'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 91Èȱ¬'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 91Èȱ¬ Nature - which includes 91Èȱ¬ Earth, Planet Earth, and all shows about wonderful wildlife around the planet! The pair will dance a quickstep.

Casualty is a 91Èȱ¬ 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 91Èȱ¬ 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 91Èȱ¬ will be broadcasting Eurovision from Liverpool - which was recently chosen to host the contest.

Fleur and Vito will be dancing a jive to Waterloo.

Grandstand was one of the 91Èȱ¬'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 91Èȱ¬ 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 91Èȱ¬ One and 91Èȱ¬ iPlayer.
