Fans have been left shocked by disturbing footage of John Lennon mocking disabled people.

The Beatles legend was an inspiration to many, but over the years his darker side has been revealed - and TV show It Was Alright In The 1960s has brought him back under fire.

In an old clip from a live performance with the Fab Four, Lennon is seen pulling faces and making exaggerated movements in an offensive manner.

The video resurfaced on the Channel 4 show this week, and it has prompted a disappointed reaction from viewers as they were reminded of the star's views.

Another added: "#johnlennon's distasteful learning disability impressions I saw on #itwasalrightinthe60s tonight would never have been OK. #beatles (sic)"

Despite Lennon's sick sense of humour being discussed by fans of the years, many were still outraged by the video.

One tweeted: "itwasalrightinthe1960s anybody who's read a bit about The Beatles knows that 'Saint' John Lennon had a cruel 'humour' about disabled people".

"That clip just confirmed what I thought #AlrightInThe60s," another said. "John Lennon was just a complete c***! You don't take the p*** out of disabled ppl (sic)"
