Standard (EADGBE)

Blue skies,

 smiling at me

 Nothing but blue skies,

do I see

Bluebirds,

 singing a song

 Nothing but bluebirds,

all day long

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

Blue days

 All of them gone

 Nothing but blue skies

From now on

Blue days

 All of them gone

 Nothing but blue skies

From now on

Extra verses:

I was blue, just as blue as I could be

Ev'ry day was a cloudy day for me

Then good luck came a-knocking at my door

Skies were gray but they're not gray anymore

I should care if the wind blows east or west

I should fret if the worst looks like the best

I should mind if they say it can't be true

I should smile, that's exactly what I do
