David Crosby

I thought I met a man
Who said he knew a man who knew
What was going on
I was mistaken
Only another stranger
That I knew
[ Lyrics from: http://www.lyricsfreak.com/c/crosby+stills+nash/laughing_20234826.html ]
I thought that I'd found a light
To guide me through my night
And all this darkness
I was mistaken
Only reflections of a shadow
That I'd saw

And I thought if I've seen someone
who's seen at last
To know the truth
I was mistaken
Only a child laughing
In the sun
