As a link between the end of the second verse and the start of McCartney's middle-eight, the band included a 24-bar bridge. At first, the Beatles were not sure how to fill this link section. At the conclusion of the session on 19 January, the transition consisted of a simple repeated piano chord and the voice of assistant Mal Evans counting out the bars. Evans' voice was treated with gradually increasing amounts of echo. The 24-bar bridge ended with the sound of an alarm clock triggered by Evans. Although the original intent was to edit out the ringing alarm clock when the section was filled in, it complemented McCartney's piece – which begins with the line "Woke up, fell out of bed" – so the decision was made to keep the sound. A second transition follows McCartney's final line of the middle eight ("I went into a dream"). This transition consists of vocalised "aah"s, reinforcing the dream aspect, and provides the link to the song's final verse.
