Yoko Ono and Lady Gaga team up

Lady Gaga performed two songs with Yoko Ono live at Los Angeles' Orpheum Theater on Saturday night (October 2).

The singer joined Ono at the end of the three-hour show to duet, reports BBC News. They ended the show lying on a grand piano together.

"Thanks for being so brilliant and such an inspiration to so many women," Gaga said of Ono from the stage. Later, writing on Twitter, she stated: "We are Plastic Ono. I got to sit in as a guest musician tonight, what a legendary band and mother, Yoko."

One of the tracks performed was the Plastic Ono Band's 'Give Peace A Chance', during which Gaga changed the lyrics to reflect her support of the campaign to overturn the US military's "don't ask, don't tell" policy towards gay service personnel.
