Who sings the song and i will love you for the rest of my life?

The lyrics actually go like this...

Just say you'll love me for the rest of your life

I gotta lot of love and I don't want to let go

Will you still love me for the rest of my life?

'Cause I can't go on

No, I can't go on

I can't go on

If I'm on my own

The name of this song is "Will You Still Love Me" by Chicago.
