Hey Nonie !!!
I did not answer last month because you mentioned you had heard this song in High School, so I figured it couldn't be the same one (about Castle Walls) that I knew of. But since you haven't had any luck so far ---- a friend of mine, Bill Ward, wrote and recorded this song about 8 years ago -- it's called Castle Walls and though it doesn't mention all of the things you talked about it's mighty close to the theme. It's on Bill's latest CD, appropriately titled "Bill Ward" and he also recorded a duet of it with Allen Damron, another local legend several years ago before they had CD's !! The cassette was called "Heroes and Sheroes". I'll e-mail you the lyrics if you like -- it may be a coincidence, BUT -----
