[Intro]
One, two

[Verse 1: Terry Kath, Peter Cetera]
Done the things I said I would
Some of them were pretty good
Suddenly, they changed the game
I only know it's not the same no more, woah

[Chorus: Terry Kath, (Peter Cetera)]
I don't know what to do, the rules I knew
Ain't it sad? (Ain't it sad?)
Ain't it true? (Ain't it true?)
Ain't it blue? (Ain't it blue? Ain't it blue?)

[Verse 2: Terry Kath, Peter Cetera]
The life I live is pretty nice
Of course I had to pay a price
Lots of folks depend on me
Erase all kinds of slavery
Oh

[Chorus: Terry Kath, (Peter Cetera)]
I don't know what to do the rules I knew
Ain't it sad? (Ain't it sad?)
Ain't it true? (Ain't it true?)
Ain't it blue? (Ain't it blue? Ain't it blue?)
[Instrumental Break]

[Interlude]
Blue, ooh ooh ooh
Blue, ooh ooh ooh

[Verse 3: Terry Kath, Peter Cetera]
Sometimes I want to walk away
I felt like that just yesterday
But when this song is in my head
I try my best until I'm dead and gone
Oh

[Chorus: Terry Kath, (Peter Cetera)]
I don't know what to do the rules I knew
Ain't it sad? (Ain't it sad?)
Ain't it true? (Ain't it true?)
Ain't it blue? (Ain't it blue? Ain't it blue?)

[Outro]
Ooh-hoo-hoo
Ooh-hoo-hoo
Ooh-hoo-hoo
Ooh-hoo-hoo
