"Tin Soldier" was originally written by Steve Marriott for singer P.P. Arnold, but Marriott liked it so much he kept it himself. It was a song that he wrote to his first wife, Jenny Rylance. P.P. Arnold can be heard singing backing vocals on the song and also performed as guest singer at television recordings of the song. The song signalled a return to the band's R&B roots whilst continuing their forays into psychedelic rock and other musical experiments. When "Tin Soldier" was released the BBC informed the band that the last line of the song had to be removed from all TV and radio broadcasts, mistakenly believing that Marriott sang "sleep with you", when in fact the lyric is "sit with you". Marriott explained that the song was about "getting into someone's mind—not their body". "Tin Soldier" reached number nine in the UK Singles Chart and remains one of Small Faces' best known songs.
