There's not much a man can do inside a prisoner   Just take his memory trips and fights the pain   And a word from home can mean so much to a prisoner   It's been years since that last letter came      Not a day goes by that I don't think of mama   And my nights are filled with thoughts of sweet Marie   And old friends I ran around with keep on running through my mind   But I just wonder if they ever think of me      I wonder if they know that I'm still living   And still proud to be a part of Uncle Sam   I wonder if they think I died of hunger   In this rotten prison camp in Vietnam      Not a day goes by that I don't think of mama   And my nights are filled with thoughts of sweet Marie   And I remember daddy sayin' you'll come back a better man   And I just wonder if they ever think of me   Oh I just wonder if they ever think of me
