Meant to say.
As for singing ' Oh Jeremy Corbyn' I only hear the crowd chanting '' oh, oh, oh, oh, oh ' which is widely chanted at sports events based on the White Stripes song ' Seven Nation Army '. The chant ' Oh, oh, oh, oh, oh ' is used at sporting events in various countries. It has been chanted for years, way before Corbyn became Leader in 2015.
At one stage in the firework display on New Year's Eve the fireworks were coordinated with popular sporting songs of which the White Stripes was one of the songs being played. Because it is a well known chant in many countries it therefore follows it be would be widely known by the crowd of various nationalities no doubt attending the London New Year celebration.
It is true to say the ' Oh Jeremy Corbyn' chant was lifted from the White Stripes, Seven Nation Army song.
