Pink Floyd - comfortably numb, 1979

"The music was composed by the guitarist, David Gilmour, while the lyrics were written by the bassist, Roger Waters, who based them on his experience of being injected with tranquilisers before a performance in 1977. Waters and Gilmour argued during the recording, with Waters preferring an orchestral arrangement and Gilmour preferring a more stripped-down arrangement. They compromised by combining both versions. Gilmour said the song was the last time he and Waters were able to work together constructively."
