Blue Skies
"Blue Skies" was a 20th century Earth song originally written by Irving Berlin. 

In 2379, Lieutenant Commander Data sang "Blue Skies" at the wedding reception of Deanna and William T. Riker, dedicating it to the happy couple. The performance was enjoyed by all, except Worf, who was not a fan of Irving Berlin. Following the destruction of Data, his "brother" B-4, who had received all of Data's memories and files, inadvertently began to hum excerpts from "Blue Skies". ()

In 2399, Jean-Luc Picard dreamed that he was playing poker with Data on the  in Ten Forward. The Bing Crosby version of "Blue Skies" could be heard over the speakers. ()

In the computer simulation that Jean-Luc Picard was in after his original organic body had died, and was in the process of being transferred into a new synth body, he met a simulation of Data, who was in a room listening to "Blue Skies" on a record player. After Jean-Luc left this simulated world, Data's program finally was shut down while this song was still playing. ()

Lyrics (excerpts) 
Never saw the sun, shining so bright,
Never saw things, going so right…
Noticing the days, hurrying by,
When you're in love, my how they fly, oh…

…Blue skies…
Smiling at me… nothing but
Blue skies…
Do I see…

Bluebirds…
singing a song…
Nothing but bluebirds… 
all day long…

Blue days, all of them gone…
Nothing but blue skies from now on…
