Lyrics

I see the hills go rushing by
I see a bird up in the sky
Choo choo, it's a trip on a train

The little child in front of me
Is not where he's supposed to be
Where is his mother? It's a trip on a train

Forgot to tip the baggage clerk
Now he's being a total jerk
Where is my luggage? It's a trip on a train

We're now at the Denver stop
I'm just about to blow my top
Just go away! It's a trip on a train

Got a souvenir for my mom
It's a little bear named Tom
Cost twenty bucks, it's a trip on a train

I think that I'll nap some more
I spilled my crackers on the floor
Damn it, damn it! It's a trip on a train

Notes

The "I took a trip on a train" vocal sample is from Frank Sinatra's "I Thought About You".
