Unforgotten theme tune: What is the song and who sings the ITV drama's title music?

Over the course of four seasons, ITV drama series Unforgotten has gripped viewers with a succession of storylines as moving as their are thrilling.

In each six-part series, detectives Cassie Stuart and Sunil 'Sunny' Khan have investigated a historical murder, first identifying the deceased, then tracking down their families and ultimately finding the people responsible for their deaths. 

Unforgotten season 5 starts on 27 February on ITV and ITVX and will star Sinéad Keenan as Jessie, who replaces Cassie (Nicola Walker) in the cold case team.

Alongside Sanjeev Bhaskar, one constant of all five seasons has been the show’s popular title music.

The haunting tune that accompanies the titles on Unforgotten is a song called All We Do. It was first used in the opening series in 2015.

Who sings All We Do?

All We Do is written and performed by Oh Wonder, a songwriting duo made up of Ant West and Josephine Vander Gucht.

They have a sizable online following and the video for the song (below) has gained more than 16 million views on streaming site YouTube. It has also been streamed 56 million times on Spotify.

Body Gold, their first song, received 100,000 listens in just three days after they put it on Soundcloud.

West and Vander Gucht began collaborating in September 2014 and released their debut album, also called Oh Wonder, a year later. The song used in Unforgotten appeared as one of 15 tracks on the album.

Oh Wonder have since followed up with two more albums: Ultralife, released in 2017, and No One Else Can Wear Your Crown, which came out in February 2020.
