Andrews said: ''Dear Lady Gaga, thank you for that wonderful tribute. Oh my God. It really warmed my heart, it really did.

''It's hard to believe that 50 years have gone by since that glorious film was released. I blinked and suddenly here I am.

''I think that I do speak for everyone connected with the movie when I say we all really felt blessed to have been a part of it and as for me, well, how lucky can a girl get?

''Great music does more than enhance a film, it cements our memories in the film-going experience.''

Other artists who took to the stage at the 87th Annual Academy Awards included John Legend and Common with a rendition of 'Glory' from the 'Selma' soundtrack and Rita Ora with an impressive vocal performance of her 'Beyond the Lights' track 'Grateful'.
