Stephen Sondheim Calls Lady Gaga's Oscar Performance a 'Travesty'

Broadway composer was not a fan of Gaga's "Sound of Music" medley.

"From what little I’ve seen, they’re so embarrassingly bad you have to sit and make fun of them or you’re just wasting your time," he said in the interview.

After Gaga brought down the house the night of the Oscars with her "Sound of Music" medley, Andrews thanked her both onstage and later by phone.

"The minute I got home from the Oscars I called her," Andrews, a long-time Gaga fan, told ABC News. "I confirmed that I thought she was fantastic and had done a wonderful job, and I couldn't thank her enough. She really did a wonderful thing with the medley.

"She sang superbly and then so lovingly handed me the evening on a platter, if you know what I'm saying."
