Kelly Clarkson is joined by all 3 ladies of Wilson Phillips to perform the group's hit single "Hold On" for a very special and exciting Kellyoke! Wilson Phillips was on Kelly's TV show yesterday and stepped onto the stage just as Kelly hit the chorus! They sound as good as they ever did and as you can imagine, Kelly's voice adds another whole dimension to the song. The harmony is so good that you'll get goosebumps. At the end of the performance, the 4 part harmony is simply amazing. Don't you just love live music? You can't fake this kind of talent!
