"Blue Skies" is a popular song, written by Irving Berlin in 1926.
The song was composed as a last minute addition to the Rodgers and Hart musical, Betsy. Although the show only ran for 39 performances, "Blue Skies" was an instant success, with audiences on opening night demanding 24 encores of the piece from star, Belle Baker.
In 1927, the music was published and Ben Selvin's recorded version was a #1 hit. That same year, it became one of the first songs to be featured in a talkie, when Al Jolson performed it in The Jazz Singer.
