Chevy Chase here s a song

Here's a song
For you who search for reason
Detailed explanations
Kept on record in town hall
I wish I could assist you
in your quizzical quest
But somehow I can't seem to think
Of any questions I would like to ask
Here's a song
To imitate the seasons
It just goes in a circle
Like the rising of the tide
I'm happy taking lessons
From the branches in the trees
I bend when I am broken
And I bend when I am shaken
By a breeze
Here's a song
To make you happy
To sing when you realize
That fish have got to swim
Birds have got to fly
But man has got to waste his time
Just always wondering why
Here's a song
For you to keep forever
The words are mine
But you can take
The meaning as you wish
I hope that it will stay around you
Longer than your doubt
I hope that you won't need to find
The answers that you're better off without
