Strictly Come Dancing viewers have labelled a BBC theme tune week "odd" and "unfair" as the show paid tribute to the broadcaster's 100th anniversary.
A special episode of the dancing contest was part of the BBC's centenary programming, with couples' routines inspired by hit shows from across the decades.
But viewers were not at all sure about the theme week - and complained that it was unfair as some contestants were given songs to dance to, while others were lumbered with difficult theme music.
One person tweeted: "I can't look away from this week's #strictly each theme tune more demented than the last."
Another person wrote: "This theme tune night is a mistake."
The line-up included Helen Skelton and Gorka Marquez performing a Charleston to the Blue Peter theme tune, James Bye and Amy Dowden dancing a Foxtrot to the EastEnders music, and Ellie Taylor and Johannes Radebe dancing a Casualty-themed Tango.

One viewer tweeted: "Tonights #Strictly Theme tune episode Has GOT to be the most trippy episode EVER! It's all VERY odd."
Someone else wrote: "Sorry this BBC theme tune thing isn’t going to work."
The music choices were popular with some viewers, as one person tweeted: "Makes you really appreciate what a perfect theme tune Grandstand had."
Someone else commented: "Christ the Line Of Duty theme tune still makes the hair on the back of my neck stsnd up!! Bring it back!!!"
However, others left viewers scratching their heads.
One person wrote: "EastEnders theme tune? Dear god."
Someone else asked: "How can you tango to the Casualty theme tune!!!! Totally bonkers."
There was also controversy as some contestants got to dance to songs instead - Fleur East was given ABBA's 'Waterloo' as a representation of Eurovision, Hamza Yassin danced to Imagine Dragons song 'On Top of the World" in tribute to nature programming, and Kym Marsh was given Sweet's 'Ballroom Blitz' rather than the actual Come Dancing theme tune.
One viewer tweeted: "I'm sorry but it's actually so unfair that Fleur & Hamza get to dance to actual songs while everyone else have to dance to stupid theme tunes. Especially Molly & Carlos, they were well & truly stitched up with the Grange Hill theme tune."
Someone else commented: "Did Come Dancing not have its own theme tune then. The answer is yes - yes it did. Not fair."
Commenting on Molly Rainford and Carlos Gu drawing the short straw with the Grange Hill theme tune, one viewer wrote: "I know it’s not technically a theme tune but I did hope they were doing a dance to Just Say No."
Strictly Come Dancing's results show airs on Sunday at 6.45pm on BBC One.
