Cape Town - Lood de Jager led the Barbarians in an animated pre-match song ahead of Saturday's clash against Argentina in London.
Any Barbarians week always places on emphasis on team spirit, and that much was evident by footage that emerged of De Jager leading the side in a song.
It is difficult to make out the words, but it sounds like the Barbarians are singing: "He'll be coming round the corner, Malcolm Marx!"
The Barbarians, which included 13 Springboks, went on to win the match 35-32 thanks to a late Elton Jantjies drop goal.
De Jager, clearly up for the occasion, went on to have a storming game for the Barbarians and scored a try on his way to a man-of-the-match effort.

No huddle or stern words.
