《地心历险记1》主题曲是《What a wonderful world》，原唱:Louis Armstrong
歌词:
I see trees of green red roses too
I see them bloom for me and you
And I think to myself what a wonderful world
I see skies of blue and clouds of white
The bright blessed day the dark sacred night
And I think to myself what a wonderful world
The colors of the rainbow so pretty in the sky
Are also on the faces of people going by
I see friends shaking hands saying How do you do
They're really saying I love you
I hear babies cry I watch them grow
They'll learn much more than I'll ever know
And I think to myself what a wonderful world
Yes I think to myself what a wonderful world
