The song World I Used To Know is performed by Glen Campbell .
Some day in some old familiar rain will come along and know my name
And then my shelter will be gone and I'll have to move along
But till I do I'll stay awhile and track the hidden country of your smile
Some day the man I used to be will come along and call on me
And then because I'm just a man you'll find my feet are made of sand
But till that time I'll tell you lies and chart the hidden boundrys of your eyes
Some day the world I used to know will come along and lead me go
Then I'll be leaving you behind for love is just a state of mind
But till that day I'll be your man and love away your troubles if I can
And till that day I'll be your man and love away your troubles if I can
