According to Tony Carey's website, the set includes all the 'Go Out Dancing' material, including alternate takes, outtakes, alternate vocals and solos, and pretty much everything that's in the drawer.

Удивительная способность Тони Кэри выпускать такие талантливые альбомы и в то же время оставаться столь не популярным. Наверное ни один из современных композиторов не написал за свою творческую карьеру столько мелодичных песен.

Planet P Project is a pseudonym used by American rock musician Tony Carey for his science-fiction themed, progressive rock/space rock music. Carey has released six albums under the Planet P Project name: Planet P (1983, later retitled Planet P Project), Pink World (1984), Go Out Dancing, Part I (1931) (2005), Go Out Dancing, Part II (Levittown) (2008), Go Out Dancing, Part III (Out in the Rain) (2009) and Steeltown (2013). Music videos for singles from the first albums received heavy to moderate airplay on MTV, when originally released. Pink World was originally a two-record set, released on bright-pink-colored vinyl.
Planet P's most well known singles were "Why Me?" (a sweeping, energetic romp about outer space and isolation), and the downbeat "Static". Go Out Dancing, Part I (1931) is the first of the trilogy, with part two titled Go Out Dancing, Part II (Levittown) and part three as Go Out Dancing, Part III (Out in the Rain).
The project's name was inspired from the fictional "Planet P" in Robert A. Heinlein's book Starship Troopers.
