The Tony Bennett effect is now fully developed. Lady Gaga completely wowed the Oscar audience last night with her “Sound of Music” medley. No more egg costumes, or meat dresses. She sang like a dream. Watch this clip. She got a standing ovation. Something really big is on the horizon for Stefani Germanotta. Someone please get her with an orchestra and a really great producer. Calling Richard Perry, Tommy LiPuma, Quincy Jones.
