 These compilation albums were also issued by the record labels to which Summer was signed (or had recently left) at the time of their releases.However, some of them were only released in certain countries (particularly if a certain label was used to distribute Summer's work exclusively in that country/those countries) and none contained any new material from Summer (although "The Donna Summer Anthology" featured two tracks from the then unreleased 1981 "I'm A Rainbow" album).Summer's first single, "Wassermann" was taken from the German cast recording of the musical "Hair" and released by Polydor Records.
