Dave Gilmour called this "The most collaborative effort of anything we ever did." In later years, the band didn't collaborate on songs nearly as much.
"The opening section is me and Roger. On 'One of these Days,' for some reason, we decided to do a double track of the bass. You can actually hear it if you listen in stereo. The first bass is me. A bar later, Roger joins in on the other side of the stereo picture. We didn't have a spare set of strings for the spare bass guitar, so the second bass is very dull sounding. We sent a roadie out to buy some strings, but he wandered off to see his girlfriend instead." - David Gilmour #PinkFloydDay #RRHK #ClassicRock #PinkFloyd #OneOfTheseDaysImGoingToCutYouUpIntoLittlePieces
