I DREAMED up the idea of the Corbyn Christmas single in early summer as a way to get out a positive message about Jeremy Corbyn.

It was really just a dream, and Christmas seemed a good target as it was comfortably far away at the time.

However, while I was thinking about a Christmas single, Robb Johnson was writing a catchy song about the Labour leader.

I heard him perform JC4PM For Me at a #KeepCorbyn gig and I knew there was no turning back. If you have heard the chorus, you will never forget it.

Robb was reluctant to front the single and wanted to make it a collective effort. But the fact he didn’t want to front it had echoes of Jeremy Corbyn himself.

The kind of person who doesn’t want to be the leader of the band is exactly the kind of person we need to lead the band.

I came up with the band name “the Corbynistas” as I thought it was two fingers up at those who use this derogatory term for supporters of the Labour leader.

As the single was for Christmas, we agreed to overdo the Yuletide cliches so no-one could accuse us of being accidentally cheesy.

At the recording, Robb added sleigh bells, a Christmas verse and a wistful xylophone.

I met Jason Harris, the graphic designer who worked on the Jeremy for Labour campaign. We wanted the artwork to reflect the fact this wasn’t an official record and was whimsical. The Christmas tree Corbyn doll with fairy lights was perfect for this.

The video was set in Hove and Brighton, where Robb lives and hangs out.

We bought Christmas jumpers, santa hats, tinsel, fairy lights, Christmas pudding and fake snow. We all had a great time and Roland Denning did a fantastic job filming and editing the video.

When a teaser for the video was released, it went viral. Nobody had ever seen such a thing!

Robb was asked to appear on The Daily Politics to discuss the single with Mike Read, the DJ and Ukip supporter.

Robb refused as he didn’t want to cosy up to someone with right-wing views. The BBC was so keen for Robb to appear that they dropped Read.

Channel Five’s The Wright Stuff played an excerpt from the video expecting it to be ridiculed, however the audience actually whooped and cheered.

The single got such media attention that a Tory decided to release a spoiler Corbyn Christmas single (however, unlike JC4PM For Me where all profits go to the Trussell Trust, the Tory will pocket half the takings from his single).

Most people have said the single is great fun but others have not been complimentary. Some have said it is “embarrassing,” while others have said it is bad idea and will actually lose Labour the next election!

It may not sit well with some more earnest comrades, but its main intention is to make people smile and pass on a message of support for Jeremy Corbyn and — like Joe Solo and the Hatfield Brigade’s Christmas single — it raises money for foodbanks.
