John Fogerty and Keith Urban have been friends for several years (you may remember they paired up for the CMT Crossroads TV program a few years ago), and last night (10.08.11) Keith invited old pal John onstage to sing 'Proud Mary' with him and the band. Here's a little clip of the two backstage first, discussing how they'll sing it together, and then the guys together on stage. http://johnfogerty.com http://facebook.com/johnfogerty http://twitter.com/john_fogerty
