Girl
The Upper Room
Through the chorus(verse is possibly the same,but log onto youtube and type in `the
room girl`,then on one live version,yo can see the frontman and his guitar very clearly)
but I know for certain,that the chorus is:
A little piece of me was calling
C, D, F
A little piece of you was falling
C, D F
Am seems to be after C in the middle-eightish bit and on the verses.
