10. Elton John/Bernie Taupin
For over 40 years Elton John and Bernie Taupin have had a very simple working relationship: Bernie writes the lyrics and Elton writes the music. It's served them well, producing "Your Song," "Tiny Dancer," "Madman Across The Water," "Burn Down The Mission" and literally hundreds of others. The two of them have never worked on a song in the same room, and they spend much of their time on opposite ends of the globe. Paired at random by a record company executive in 1967, Taupin/John is one of the most successful and long-lasting partnerships in the history of popular music.
