I second the love for English Trees. "Nothing's sadder I know, than the passing of time" always gets me. It may have something to do with my long-term eidetic memory. It's uniquely saddening to have memories that are so vivid and near in my mind grow so distant in actual time.
But probably my three favourite middle eights come from Together Alone (where most of my favourite anythings come from).
Nails In My Feet, Private Universe, Fingers of Love (the hint is in the username)- all of those middle eights nearly make me melt.
To me, "English Trees" is one of the greatest songs Neil has ever written and one of the greatest songs ever written by anybody. The song has so much depth and subtle brilliance both lyrically and musically. And the studio version completely nails it. The way Neil takes the incredible 2nd verse ("the chords entwined like a requiem") into the "nothing's sadder I know than the passing of time" bridge and then closes the song with the "English trees in my garden, all of your crimes are forgiven" refrain is simply majestic. How a human being came up with this is beyond me.
"They lose their leaves in the winter
Mark the seasons for him and for her
Once upon a time in the fallen snow
Up against the sky made a silhouette show
England cries and she plays for him
The chords entwined like a requiem
Although it's springtime and color is new
In Regent's Park I will mourn for you
And I must be wise somehow
'Cause my heart's been broken down
It's so far to fall
And so hard to climb
Nothing's sadder, I know
Than the passing of time
Won't forget me
You won't forget me"
