On Saturday, November 19, Katharine McPhee joined her mom, Peisha McPhee, and sister, Adriana McPhee,  for a special concert called “A Family Affair” at the Irvin Barclay Theatre in California.

Katharine performed “Sisters”, “If Momma Was Married” and “Mama, A Rainbow” together with her sister Adriana. Later on, Katharine’s husband David Foster took the stage and invited Katharine back to bring the audience a little Christmas spirit by performing “Rudolph the Red-Nosed Reindeer” from their new holiday album, ‘Christmas Songs.’ They also entertained the audience with Katharine’s signature rendition of “Somewhere Over the Rainbow” and “Singing in the Rain” before Peisha came back to the stage.

At the end of the show, all performers joined the stage to perform “That’s Life”.
