The poem went No body knows but me

Answer 1

"Nobody Knows It But Me"

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 wherever you're going

That's wherever you are

And nobody knows it but me

Answer 2

Here is the link to the poem, and a bit of info about the commercial as well.
