Barbra at the 85th Annual Academy Awards

For the first time in 36 years, Barbra's return to the Academy Awards was during the show's In Memoriam montage, which concluded with the image of The Way We Were composer Marvin Hamlisch.

This was Barbra's first Live-singing appearance on TV since 2001 (not including pre-recorded "live" TV appearances). 'Marvin Hamlisch was a composer of extraordinary depth and versatility,' said Barbra. 'He was also a very kind and generous friend who could always make me laugh. Over the years, we shared many adventures together.

 'Marvin left us way too soon, but I'll always have those wonderful, wonderful memories.'

Barbra was trending on twitter during and after the performance... with some fantastic comments....
