Bee Gees
From Tardis Wiki, the free Doctor Who reference
The Bee Gees were a music group on Earth that Melanie Bush liked in her youth. (PROSE: Business Unusual)
All River Song could remember from the karaoke night she spent with the Eleventh Doctor and Jim the Fish was the song "Islands in the Stream", and a tape recorder, which was been lost. (GAME: The Eternity Clock)
