From the Wikipedia entry for Daylight Saving Time:

The musical standard "(There Ought To Be A) Moonlight Saving Time" by Irving Kahal and Harry Richman was a #1 hit for Guy Lombardo in 1931, and was also performed by Maurice Chevalier, Blossom Dearie and others. Moonlight saving time also appears in the 1995 country song "Not Enough Hours In The Night" written by Aaron Barker, Kim Williams and Rob Harbin and performed by Doug Supernaw.

Coldplay's song "Clocks" was co-written by Chris Martin, great-great grandson of DST inventor William Willett. It won the 2004 Grammy Award for Record of the Year. Its first line is "Lights go out and I can't be saved".

THERE OUGHT TO BE A MOONLIGHT SAVING TIME
Kahahl and Richman

INTRO:
Birdies fly with new ambition, Spring is in their song!
Soon you'll find yourself a wishin' days were not so long.
If my thought is not defined, listen while I speak my mind:

REFRAIN:
There ought to be a moonlight saving time, So I could love that gal of mine,
Until the birdies wake and chime Good morning!
There ought to be a law in clover time To keep that moon out overtime
To keep each lover's lane in mind 'til dawning.

BRIDGE:
You'd better hurry up, hurry up, Hurry up get busy today!
You'd better croon a tune, croon a tune, To the man up in the moon,
And here's what I'd say:
