The track is featured on The Letter/Neon Rainbow. The song starts with the lyrics "The city lights, the pretty lights, They can warm the coldest nights" and as they suggest, the song is about neon signs that come on at night and make even the city's coldest nights seem warm. The lyrics continue "But in the daytime everything changes, Nothing remains the same. No one smiles anymore, And no one will open his door. Until the night time comes. And then the..." suggesting that the city's inhabitants stay inside during the day and come out only at night.
Petula Clark recorded the song for her 1970 album Memphis and Rita Pavone made an Italian version with the title "Il mondo nelle mani" (The world in the hands).
