Carrie Underwood will appear as herself along with crooner Tony Bennett on the second season premiere of the CBS TV drama ‘Blue Bloods’.  Carrie and Tony will sing together as themselves during a fundraiser scene on the show September 23.  They will cover the song “It Had to Be You” which is part of Bennett’s Duets II CD hitting stores on September 20th.  The show ‘Blue Bloods’ stars Tom Selleck and Donny Wahlberg.  I watched the first season and really liked it, so I was glad to hear the network renewed it for a second season.
