The song that lifts me when there's doom and gloom,
is 'Tomorrow' from the musical, Annie.
The song, written by the composer Charles Strouse and lyricist Martin Charnin, has been a prominent feature of the musical throughout its history.
The musical was based on a 1920's comic strip 'Little Orphan Annie', a string of episodic and unrelated adventures in the life of an 11 year old orphan girl who wanders like an innocent vagabond through a corrupt world. The major players being Annie, her dog Sandy and 'Daddy' Warbucks, a billionaire businessman and Annie's benefactor.
The original Broadway production opened in 1977 and ran for 6 years, winning seven Tony awards including one for best musical.
The clip below is a medley of a few of the songs from the 1977 musical with the original cast members including the 14 year old Andrea McArdle in the role of Annie on the Tony Awards Show.
