Lady GaGa channelled Judy Garland's iconic portrayal of Dorothy in The Wizard of Oz for a live performance on U.S. Tv on Monday morning (09Sep13).

The singer started her performance on Good Morning America by singing the 1939 film's famous anthem Over the Rainbow, dressed in a black wig, blue gingham dress, red sparkly shoes and clutching a small dog in a basket.

She was surrounded by dancers dressed as the film's characters the tin man, the scarecrow and the cowardly lion, who joined in with her as she broke into a rendition of her new single Applause on a stage which was made up as the yellow brick road.

Another dancer performed as one of the film's iconic winged monkeys, while Gaga made a quick change into a pink costume with a blonde wig, clutching a magic wand in reference to the movie's good witch character, Glinda. She then peeled off the outfit for a showdown with the Wicked Witch of the West.

After a fourth costume change during the short set, Gaga finished the show in another blue and white outfit, complete with an oversized bow on her head, telling the Gma host, "I'm so happy to be here - there's no place like Good Morning America!"

Before the performance, Gaga asked all the members of the audience to wear special hats designed to look like poppies.
