More flack for the lacklustre ceremony:

Dr David Lindfield writes: The most boring ever, I can't watch and am just looking at the BBC for the results.

Ernesto Migoya writes: Neil Patrick Harris is an idiot and should not be invited back to be a host.

Collecting the award to another standing ovation, John Legend said: "Nina Simone said it was an artist's duty to reflect the times we live. Selma may be 50 years ago, but it is now, because the struggle for justice is right now.

"The voting rights they fought for are being compromised right now, today. We live in the most incarcerated country in the world. There are more black men in prison than were in slavery.

"When people are marching with our song, we tell you we see you - and we march on."

Idina Menzel and John Travolta are together on stage - a year after the latter famously stumbled on Menzel's name when introducing her perform Let It Go.

Introducing them, host Neil Patrick Harris quips: "Benedict Cumberbatch - the sound you get when you ask John Travolta to pronounce Ben Affleck."

It seems some Oscars viewers are starting to feel a bit weary:

• Richard Hill tweeted us, external his verdict: "Thought Neil Patrick Harris would be better - jokes are lame, and too many pauses. Getting bored..."

• Louise Mensch tweets, external: "I love #Whiplash but I'm giving them 15 minutes to get to best adapted or I'm going to bed. #Oscars2015 #hiresomewriters."

• Katie Couric ‏tweets, external: "It's official. I'm bored."

The In Memoriam section also got people talking:

• Peyton's Head tweets, external: "Sorry, you can't stick Robin Williams in the middle and then use a drawing that doesn't look like him."

• Mike Lawrence tweets, external: "I lost two dollars betting Robin Williams would be last in the death montage. I'm sad all over again."

• Marcus Errico tweets:, external "While #ERedCarpet @eonline gave tribute to #JoanRivers in preshow ceremonies, #Oscars2015 In Memoriam left her out. Really, Academy?"

John Legend and Common take to the stage now to perform Glory from Selma.

Their rousing song complete with choir drew a standing ovation from the audience, as well as a few tears.
