One of my favorite bands of all time is Creed. I could listen to them all day.
 Creed was an American rock band
Do you know when the band was formed?
Yes, it was formed in 1993 in Tallahassee, Florida
Who were the members? I know the lead singer was Scott Stapp.
You are right, it  hads  lead vocalist as  Scott Stapp, guitarist and vocalist Mark Tremonti, bassist Brian Marshall, and drummer Scott Phillips
I wonder what those guys are all doing now. Did Creed officially break up or are they just on a long break?
Yes they did,  the band disbanded in 2004 due to increasing tension between members.
