Which studio album first included the solo version of "Rein Me In"?

People Watching was the first studio album to include the solo version of “Rein Me In.”

The song appeared on Sam Fender’s third studio album, People Watching, released in 2025. On the album recording, Fender performs the song alone; Olivia Dean joined him for the later duet version that became associated with the single’s chart success.

That timeline creates the main possible mix-up. The duet is often treated as the best-known version, but it was not the original album recording. The collaboration emerged after the song had already been released, giving the track a second life as a Fender-and-Dean release.

People Watching is also the name of the album, while “Rein Me In” was later listed on its deluxe edition in its collaborative form. The title is sometimes confused with Fender’s earlier albums, Seventeen Going Under and Hypersonic Missiles, but neither contains the first solo album version.
