(Merle Haggard/Bonnie Owens)   Danial O'Donnell & Mary Duff      Somewhere between your heart and mine   There's a window that I can't see through   There's a wall so high it reaches the sky   Somewhere between me and you.      I love you so much I can't let you go   And sometimes I believe you love me   But somewhere between your heart and mine   There's a door without any key.      Somewhere between your heart and mine   There's a window that I can't see through   There's a wall so high it reaches the sky   Somewhere between me and you.      --- Instrumental ---      Somewhere between your heart and mine   There's a love I can't understand   Oh, it's there for awhile then it fads like a smile   And I'm left in the middle again.      Somewhere between your heart and mine   There's a window that I can't see through   There's a wall so high it reaches the sky   Somewhere between me and you.      Somewhere between me and you...
