The first part Lennon composed 1957. Not until in spring 1964 - Lennon's very productive year - he composed the middle part. Lennon could create enormous power in his compositions with seemingly limited means: The middle part has only one melody, but in three different ways. This creates a feeling of desperation.
The three variations in the middle part end in the same note, but are emphasized in different ways:
1) "take it..."
2) "who can...
3) "ya take it..."
At the same time a counter melody in a guitar binds the three variations. The middle part is almost exactly the same as the middle part in Lennon's "And Your Bird Can Sing
