Jesus College alumni Clean Bandit have secured Christmas Number One with their single “Rockabye”.

The electronic trio, who met at Cambridge, held on for the seventh consecutive week to clinch top spot for Christmas, the longest reign this year apart from Drake’s fifteen-week stint with “One Dance”.

Although Clean Bandit were overwhelming 1-50 favourites with the bookmakers to take the prize, the band nonetheless had to fend off competition from this year's X-Factor winner Matt Terry, and 2011 champions Little Mix.

In the end, the closest competition was from Rag'n'Bone Man who took number 2 with his track "Human", with "Just Hold On" by ex-One Direction member Louis Tomlinson and Steve Aoki just behind in third place.

Elsewhere in the charts, this year’s charity singles failed to threaten the top spots, with the London Hospices Choir and a single released in memory of murdered Pembroke alumna Jo Cox MP both failing to make the top 40.

Christmas favourites were, as always, a strong presence, with nine festive songs making the top 40. Slade's "Merry Xmas Everybody" re-entered the charts at number 39, "I Wish It Could Be Christmas Everyday" finished at 27, the ever-popular "Fairytale of New York" charted at number 15, and Mariah Carey's "All I Want For Christmas Is You" was the best performing Christmas song at number 5.

“Rockabye” is Clean Bandit’s second number one hit, following 2014’s “Rather Be”, for which the band won a Grammy for Best Dance Recording, and the first single for the band since the departure of pianist and violinist Neil Amin-Smith in October.

Speaking to Varsity, Jesus College JCR president Katherine Boucher said, “we're delighted that Clean Bandit have taken Christmas Number One. It was great to have them return to Jesus this year to play at the May Ball and we've been backing them all the way.”
