[Chorus: Peter Cetera]
Yesterday I would not have believed
That tomorrow the sun would shine
Then one day, you came into my life
I am alive again
I am alive again

[Verse 1: Peter Cetera with bandmates]
All the empty yesterdays have disappeared
Now that you have filled my life with love
No one else could ever mean so much to me
Every day my high lasts longer
As our love grows ever stronger

[Chorus: Peter Cetera, with bandmates]
Yesterday I would not have believed
That tomorrow the sun would shine
Then one day, you came into my life
I am alive again
I am alive again

[Verse 2: Peter Cetera with bandmates]
When you gave your love to me, you changed my life
Dreams that once seemed hopeless, come with ease
Thank you, girl, for being just the way you are
I would never try to change you
All I live for is to love you
[Bridge: Peter Cetera]
I'm feeling alive
I'm feeling alive again
Don't you know I'm feeling alive?

[Outro: Peter Cetera with bandmates, (Peter Cetera)]
Yesterday (I would not have believed)
That tomorrow (The sun would shine)
Then one day (You came into my life)
I am alive again
Yesterday (I would not have believed)
That tomorrow (The sun would shine)
Then one day (You came into my life)
I am alive again
Yesterday (I would not have believed)
That tomorrow (The sun would shine)
Then one day (You came into my life)
I am alive again
Yesterday (I would not have believed)
That tomorrow (The sun would shine)
Then one day (You came into my life)
