Within the prison of my soul Locked within my troubled mind Is a love I can't forget 'Cause she's just one of a kind Just a plain old fashioned girl The kind a man don't have to tame When he starts to settle down He's proud to let her wear his name Within my hand I hold the key Do I dare to set her free Got a feelin' in my mind That she's just one of a kind Pulled away from my hometown Thought I'd leave her love behind But Mary rode with me On the highways of my mind Seen a million pretty girls Pretty girls aren't hard to find But she's a rare breed, I'm convinced Mary's just one of a kind Within my hand I hold the key Do I dare to set her free Got a feelin' in my mind That she's just one of a kind Within the prison of my soul Locked within my troubled mind Is a love I can't forget 'Cause she's just one of a kind
