engineers and other abbey road staff have reported that the beatles would try to take advantage of accidental occurrences in the recording process; "i feel fine" and "it's all too much"'s feedback and "long, long, long"'s resonating glass bottle (towards the end of the track) are examples of this. in other instances the group deliberately toyed with situations and techniques which would foster chance effects, such as the live (and thereby unpredictable) mixing of a uk radio broadcast into the fade of "i am the walrus" or the chaotic assemblage of "tomorrow never knows".
