This is a short easy piano version of Moon River by Frank Sinatra written for beginner pianists. I have adult students who want to play their favourite jazz and pop songs, so I usually make a rearrangement of those songs and make it easier for them to play.
This music has fingerings and necessary articulations. Just two pages long and just has first verse but you may like to repeat it over and over.
Watch the below video for an idea of how it sounds like.
