Mike - It's a verse from a song that means a great deal to me - by Michael Kelly Blanchard called "Be Ye Glad". Probly on Youtube too. You can find all the lyrics by seaching his name and the title of the song. I had to edit it drastically to get it under the allowed length for signature lines. First time i heard it i thought - that is mine!
"That you are here - that life exists, and identity; that the powerful play goes on and you may contribute a verse. . . What will your verse be?" Robin Williams as John Keating in "Dead Poets Society"
