about intonation of a poem

Hi, hope this is the right forum for this post.

The words "I remember" appeared 5 times below and they don't have the same meaning. I feel that no. 2,3,4 are kind of meaningless (Is "filler" the right term?) and should read with a rising tone. No. 1 certainly has meaning and read with a flat tone. But how about no.5 ? I heard someone read it with a flat tone (or falling tone) but I feel that it is meaningless as well. Any comments.

(the same person read 2,3,4 with rising tone and 1 with flat tone, which I agree)

It Was Long Ago

I'll tell you, shall I, something I remember (1)?

Something that still means a great deal to me.

It was long ago.

A dusty road in summer I remember (2),

A mountain and an old house, and a tree

That stood, you know,

Behind the house. An old woman I remember (3)

In a red shawl with a grey cat on her knee ...........

And that is almost all I can remember,

The house, the mountain, the grey cat on her knee,

Her red shawl, and the tree,

And the taste of the berries, the feel of the sun I remember (4),

And the smell of everything that used to be

So long ago,

Till the heat on the road outside again I remember (5),

And how the long dusty road seemed to have for me

No end, you know.
