"Big, Big Heart" lyrics

I've got a train inside my heart, oh how it rides
Filled with love, that's how the engine starts
Would you like to take a ride
In the carriage by my side?
Riding through my big, big heart

Many stops along the way
Traveling night and day
The end of the line is only just the start

All aboard, let's take a ride
In the carriage by my side
Riding through my big, big heart

Who's in your heart?
Oh, I'll tell you who's in my heart too
You were in our hearts
Oh, and Wiggles, you're in my heart too
And we all love you

You've got a train inside
Your heart, oh how it rides
Filled with love, that's how the engine starts
Can I take 'em for a ride
In the carriage by your side?
Riding through your big, big heart
Riding through your big, big heart
Riding through your big, big heart
