The Beach Boys - In the Back of My Mind lyrics

I'm blessed with everything A world to which a man can cling So happy times when I break out in tears In the back of my mind I still have my fears I live my life with her Love her true she knows I'm sure I make her happy just living so plain In the back of my mind I'm 'fraid it's gonna change I tried to run far way from thoughts I should try to keep away But they just keep coming back to me I tried to rationalize But some day I might realize That things are just good the way they'll be I know it's so hard to find A girl who really understands your mind What will I do if I lose her It will always be way in the back of my mind
