VIDEO: GORDON LIGHTFOOT: IF YOU COULD READ MY MIND

One of the most beautiful songs ever. The supposed meaning of the song is under the lyrics for those interested.
If you could read my mind, love
What a tale my thoughts could tell
Just like an old-time movie
'Bout a ghost from a wishin' well
In a castle dark or a fortress strong
With chains upon my feet
You know that ghost is me
And I will never be set free
As long as I'm a ghost that you can't see

If I could read your mind, love
What a tale your thoughts could tell
Just like a paperback novel
The kind the drugstores sell
When you reach the part where the heartaches come
The hero would be me
But heroes often fail
And you won't read that book again
Because the ending's just too hard to take

I'd walk away like a movie star
Who gets burned in a three-way script
Enter number two
A movie queen to play the scene
Of bringing all the good things out in me
But for now love, let's be real
I never thought I could act this way
And I've got to say that I just don't get it
I don't know where we went wrong
But the feeling's gone and I just can't get it back

If you could read my mind, love
What a tale my thoughts could tell
Just like an old-time movie
'Bout a ghost from a wishin' well
In a castle dark or a fortress strong
With chains upon my feet
But stories always end
And if you read between the lines
You'll know that I'm just tryin' to understand
The feelings that you lack
I never thought I could feel this way
And I've got to say that I just don't get it
I don't know where we went wrong
But the feeling's gone and I just can't get it back

Some comments I read somewhere. Maybe the true meaning:

Many people interpret this as a song of regret. It is not. It is a song of sorrow, not regret. Leaving his wife is something he understands that he must (unfortunately) do. He is sad about it and has sympathy for his wife. But leave he must before something worse and regrettable happens.

While the Gordon may have eventually acquired "feelings" for other women (which may be what he is referring to in "I never thought I could act/feel that/this way".....I am not sure), that is not what caused this relationship to fail.

The most important and powerful words in the song are in the last verse:

And if you read between the lines
You'll know that I'm just trying to understand
The feelings that YOU lack

These lines are so powerful and personal that Lightfoot's (now grown up) children from this broken marriage have requested that he use the line "the feelings that WE lack" (which changes the true meaning of the song, IMO) when he now performs this in concert. Gordon has honored their request.
