a) Does he have a song entitled “After All” which mentions the lyrics “two angels who’ve been rescued from the fall…”
b) Does he have a GH with all the duets he’s done?
Thanks, Jinx
“After All” was a Cetera duet with Cher. (I think it was Chere, anyway)
A) Yes, and psifireus is right, it was with Cher
B) Not to my knowledge, no.
Major Peter Cetera fan checking in. [ducks…runs for cover]
Jinx, check out You’re The Inspiration - A Collection (1997): Peterceterafanclub.com
All sorts of good duets on that album. 
Shhh…I had “Solitude/Solitaire” on cassette. shuffles feet
I always did like “Glory of Love” and “Will You Still Love Me”
:o
FWIW, wasn’t Will You Still Love Me performed by Chicago?
That is, by Chicago post-Cetera.
Yeah, Will You Still Love Me was from Chicago 18, the first “AC” album (After Cetera), as the group likes to say.
The “AC” era Chicago has had a couple good songs, but it’s pretty much been downhill for them ever since Cetera left.
BTW, Peter Cetera is going to be doing Symphony Tour this year, with limited dates. One of the shows is going to be filmed for a PBS special. If he swings our way, my wife and I are so there! And he better sing Baby What A Big Surprise or we are going to be pissed! PISSED I SAY!!
The year: 1978
The place: The Fabulous Forum, Los Angeles, California
The event: Chicago in concert.
The fun part: Peter Cetera singing “Baby What A Big Surprise” and forgetting the words.
I still am a big Chicago/Cetera fan. He has probably the most unique voice in all of music - you hear Cetera, you know instantly it’s him.
