Well, I posted this a while back, but like to never have found it again. So, since you specifically asked for songs about Daylight savings time, I'll post it again.

Simani (Sim Savoury and Bud Davidge of Newfoundland) has a pretty good commentary on the situation.

Double Daylight Savings Time

Uncle Tom's watch used to shine in the dark
But he gave her a weegie out over the wharf
Don't need her now boys, Uncle Tom said
Since the new daylight savings time scheme was brought in

Who thought it up boys, God love his heart
Tis wonderful seeings our summers so short
With twice as much sunshine, Oh Lord, bless us all
I low we'll be burned up as black as the coal

Double your pleasure, double your fun
For half of the year, we'll have double the sun

The man down at U. I. was scratching his head
Get some funny letters here lately he said
Like if I had enough double daylight punched in
Do you think that me five weeks could pass off for ten

Me grandfather's just about 90 years old
He can't seem to get what is happening you know
All his life he's been up at the crackin' of dawn
Now dawnin' don't crack 'til the day's almost gone

A frisky young feller who lives up the bay
He now hauls his lobster pots twice every day
And got plenty of time when his fishing is through
To burn up some pork chops on his gas barbeque

Double your pleasure, double your fun
For half of the year, we'll have double the sun

Some says it's bad while others says good
Savings on kerosene, shocking on wood
And mothers who can't get their youngsters to bed
Can't sleep cause they got too much light in their head

But supposin' we lived where the sun never sets
Where half of the year the lamp's never lit
So make like the Eskimos living up North
Pull down your blind and your igloo goes dark

Double your pleasure, double your fun
For half of the year, we'll have double the sun
With double the daylight, we'll double the fun.

Sandy, I have a song about Moonlight Savings Time ~~ somewhere. I will try to think to look it up.
