《I'm Back》的詞曲作者是孫國榮，歌詞如下：
I'm back, I'm back, I'm back in business
I'm back, I'm back, I'm back in the place where I started from
Chorus:
I've been away so long
But now I'm back where I belong
And all the places that I've been in between
I'll leave behind
Verse 2:
I've been up, I've been down
And everywhere in between
But now I'm here to stay
And let the world know
That I'm back
Chorus:
I've been away so long
But now I'm back where I belong
And all the places that I've been in between
I'll leave behind
Bridge:
This time when I leave it's for good
I won't be coming back no more
I'm moving on to new adventures
That are waiting for me somewhere up above
Chorus: (repeats to fade)
Now that I'm back where I belong
No more up and down
I'm making a new start
And the world will soon be aware of
Who I am and where I'm going from here...
Now that I'm back... (x2)
