You Are the Sunshine of My Life  is a 1973 single released by Stevie Wonder.
You Are My Sunshine The other night dear, as I lay sleeping I dreamed I held you in my arms But when I awoke, dear, I was mistaken So I hung my head and I cried. You are my sunshine, my only sunshine You make me happy when skies are gray You'll never know dear, how much I love you Please don't take my sunshine away.
