I've been searching
For a pot of gold
Like the kind you find
At the end of the rainbow
I've been dreaming
Thought it was in vain
Ah, but now you're here
Can't believe that you're back again
Now I know I can't lose
As long as you follow
I'm gonna win
I'm gonna beg, steal, or borrow
As long as you follow
I've been wandering
Gone away too far
But the road was rough
To get back where you are
And the sun went down
It never seemed to rise
Ah, but now you're here
With the light shining in your eyes
Now I know I can't lose
As long as you follow
I'm gonna win (I'm gonna win)
I'm gonna beg, steal, or borrow
Yes, I can live today
If you give me tomorrow
As long as you follow
[Instrumental]
Now I know I can't lose
As long as you follow
I'm gonna win (I'm gonna win)
I'm gonna beg, steal, or borrow
Yes, I can live today
If you give me tomorrow
As long as you follow
As long as you follow
(As long as you follow)
As long as you follow
(As long as you follow)
As long as you follow
(As long as you follow)
(As long as you follow)
(As long as you follow) FADES OUT
This song seems to suggest there was a break up and now they're together again. The underlining issue for the singer is that he travels a lot, given the industry he's in, and he's saying "I'll beg, steal and borrow" (for you) as long as you follow. As long as you follow indicating staying by his side while touring or gone for long time or in the craziness of the music industry.
Thats my interpretation of it. Doesn't mean its correct. this is my rational.
