The poem in the Chevrolet Tahoe commercial is called "Nobody Knows It But Me" written by Patrick O'Leary with the voice-over by James Garner. The words of the poem are as follows:

There's a place that I travel
When I want to roam
And nobody knows it but me.

The roads don't go there
And the signs stay home
And nobody knows it but me.

It's far far away
And way way afar
It's over the moon and the sea
And whenever you're going
that's wherever you are
And nobody knows it but me.

That's beautiful. More commercials should be an introduction to poetry. It reminds me a bit of a fragment of a poem (the rest of which is lost to the dust of memory) called Green Banana Moon. I don't remember the dream portions, but instead only the refrain sticks in my noggin. Perhaps later I'll be able to pry the rest free later.

every night we see a moon
it never looks the same
there's one that's full
and one that's sliced
and one that has a name.

searching with its moonbeam
its glow will find us soon
and once it does
we're sure to dream
beneath the green banana moon.

I'd like to take hold of my beloved and dream with her right now under the green banana moon. Happy dreams. pleasant waves of bliss and cheer.
