Jenny Wren Lyrics
But a broken heart, took her soul away
She could see the world, and it's foolish ways
Loosing, site of life, day, by, day
Wounded warriors, took her song away
When this broken world, mends its foolish ways
All be-cause of you, Jenny Wren

it's called the sequel to 'blackbird'
quite a beautiful song and my name is jenny so i like it a bit more haha

I just couldn't tell ....

Stanza 1-Jenny Wren was young and naive and had a song in her heart. Stanza 2-Then she saw the cruelties of life and in the world and became disillusioned. Stanza 3-We should make an effort to be more compassionate so more young people won't become saddened by the world.

It is on the end of the song that I disagree with Bryia 026: The song doesn't say that she has to make an effort, but that the world will change, one day. This is a statement of hope in mankind.

I found this info about the song on Wikipedia:
Jenny Wren was written in Los Angeles, and is about a character of the same name from Charles Dickens' novel Our Mutual Friend. It also refers to an English bird known as the wren, which is reported to be McCartney's favourite. McCartney wrote the tune in the same sort of finger picking style found in "Blackbird", "Mother Nature's Son" (The Beatles) and "Calico Skies" (Flaming Pie).
