"Two of Us" is found on both Let it Be and Let it Be ... Naked. They share formal structures, but the timings are different due to the inclusion of studio chatter in the introduction of the album, which was omitted on Naked.
Formal structure of  "Two of Us":
Comments: This one's pretty simple and straight-forward structurally. I debated over whether or not to divide the verse into a verse and chorus where the meter changes to triple, but chose not to because despite using the same lyrics each iteration it simply doesn't have enough of an energy increase to justify that labeling.
The use of a tag is textbook - it introduces the first two verses, and returns in the coda.
