"Comfortably Numb" has its origins in Gilmour's debut solo album, and was the source of much argument between Waters and Gilmour. Ezrin claimed that the song initially started life as "Roger's record, about Roger, for Roger", but he thought that it needed further work. Waters changed the key of the verse and added more lyrics to the chorus, and Gilmour added extra bars for the line "I have become comfortably numb". Wright's "stripped-down and harder" recording was not to Gilmour's liking; Gilmour preferred Ezrin's "grander Technicolor, orchestral version", although Ezrin preferred Waters's version. Following a major argument in a North Hollywood restaurant, the two compromised; the song's body included the orchestral arrangement, with Gilmour's second and final guitar solo standing alone.
