help identify this song and the musical it came form

There's got to be a reason for living on this earth
There's got to be a reason...
For taking the space I take
Breathing the air I breathe.
There's more to this theres more to me
something in me that needs to
do more than suck the breathe from life
like leaves and bees and trees do
holding up my head
holding down a place
holding up my name to
go with my face.

The song is called 'I've Got To Find A Reason' and is from the musical 'Carvival'
