"Moon River" is a song composed by Johnny Mercer (lyrics) and Henry Mancini (music) in 1961, for whom it won that year's Academy Award for Best Original Song. It is most well-known for being sung in the movie Breakfast at Tiffany's by Audrey Hepburn, although it has been covered by many other artists.
Moon river, wider than a mile
I'm crossing you in style some day
Oh dream maker, you heart breaker
Wherever you're going, I'm going your way
