Mythology is a box set compilation of recordings by the Gibb Brothers, mostly performed as the Bee Gees, arranged in a four disc set each highlighting a Gibb brother. Barry and Robin chose their own songs (presumably their personal favourites), with Maurice's songs selected by his widow Yvonne and Andy's songs selected by his daughter Peta. Several U.S. and U.K. hits are absent from this collection including "Lonely Days", "How Can You Mend a Broken Heart", "You Should Be Dancing", "Nights on Broadway", "World" and "One".
