Video - The Barbarians pre-match song that's deservedly going viral

The Barbarians are renowned for their sense of humour and their espousal of the old-school ‘social’ value of rugby union.

That was on full display in the home dressing room at Twickenham before their try-fest encounter with Argentina yesterday.

A video taken before the match of their pre-match sing-song has gone viral. Led by giant Springbok secondrow Lood de Jager, their take on ‘He’ll be coming round the mountain’ is quite the ditty.

And it seemed to get the team pumped up too, with the big man himself getting over the line.

Fans got full value for money as Elton Jantjies’ late drop-goal completed a stunning comeback for Barbarians, who ultimately beat Argentina 38-35.

The Baa-Baas, made up largely of South Africa players and led by Springboks head coach Rassie Erasmus, found themselves 28-7 down inside half an hour and were still trailing by a converted try with five minutes to go.

It was one of the Pumas’ usual stalwarts, Juan Manuel Leguizamon, selected by the Baa-Baas, who got the scoring under way as superb hands down the right involving Siya Kolisi and Schalk Brits sent him free.

That try was celebrated by the number eight rolling the ball into his team-mates, who fell to the ground like bowling pins, but the lead was swiftly wiped out as Matias Orlando showed quick feet to round Luke Jones after Handre Pollard’s ill-advised chip from his own line, and the Pumas were in front when Joaquin Diaz Bonilla kicked through for Ramiro Moyano to dot down.

But de Jager’s score – the 10th of the match – brought the invitational side level and, with a minute left on the clock, Jantjies slotted over a drop-goal to provide a fittingly dramatic conclusion to what had been an entertaining contest.

The late twist capped a disappointing tour for the Pumas, who over the past three weekends had suffered defeats at the hands of Ireland, France and Scotland in a worrying sequence of results ahead of next year’s World Cup.
