Harry Chapin's "Changes" - 1st verse seems to apply to Agent Orange

[AZLD4Candidate]

I was cramped into a coffee house pew
Two dollar coke in my hand
Listening to the music run
Through and out of a drowning man
Ten years ago I first heard him singing
To a screaming crazy crowd
Now there's thirteen loyal people
Trying to sound that loud
And I wonder as I watch him now
Why his songs don't turn me on
He got me into music
Where has the fragile magic gone?

And all the changes
Keep on changing
And the good old days
They say they're gone
Only wise men
And some new born fools
Say they know what's going on
But I sometimes think the difference is
Just in how I think and see
And the only changes going on
Are going on in me
