Six Nations 2012: Wales' 'Hair Bear' Adam Jones wins vote of approval from London Mayor Boris Johnson The politician was even invited to attend Jones's testimonial dinner at London Welsh on Thursday night at Old Deer Park in Richmond, along with Wales coach Warren Gatland and team-mates such as Alun-Wyn Jones and Ryan Jones. Johnson's busy diary meant he had to decline the invitation but he has written a glowing tribute to Jones in his testimonial brochure. "Adam plays rugby with fire in his belly, steel in his spine and that mad mop of hair on his head," Johnson said. Anyone in public life with hair like that gets my vote - especially when they put their neck on the line and pull out all the stops for their colleagues. As a tighthead in far humbler contests I've watched him in awe, and was thrilled to witness - first hand - his fabulous try in February 2010. Having spoken to him on the eve of that critical World Cup semi-final game I was gutted to see Adam leave the field. The front row may not be the most glamorous position but it is the front line and the cornerstone on which all great performances are built. Adam is a tribute to his club, his country and his sport and I wish him well with his testimonial. Jones, widely regarded as one of the best tightheads in world rugby, admits he has been a little flummoxed to have such a high-profile supporter. Those who ply their trade in the front row are not normally used to such moments in the limelight. "It was a bit of a shock but nice to have someone of that profile as a fan," said Jones, whose scrummaging prowess earned him cult status on the Lions tour of South Africa in 2009. I was taken aback but obviously he is a bit of a legend, you see him on TV. I don't know too much about what he does for London, but everyone knows he is the Mayor and he is a top man. He said to me he used to play prop forward himself at school I think and I tend to stand out from the other props - I would like to think it is because of my ability and not just my hair! He is comfortably my most famous supporter I would have thought. Jones recalls the nerves he felt waiting for Johnson's call in Auckland, the night before Wales narrowly lost to France in the World Cup. He had spoken to my wife, Nicole, earlier in the afternoon and she told me Boris Johnson had been on the phone and was going to phone in half an hour. "I was a bit nervous, because I didn't know what I was going to say to him," added Jones, who will win his 78th cap for Wales on Saturday. We had a quick chat for about five minutes, he wished me well. Whatever came out of my mouth probably didn't make any sense. I think I was talking rubbish, but it was great. The pair have yet to meet, but Jones is hoping to catch the Mayor, who insists he will still be cheering for England on Saturday, for a pint at Twickenham after the match. "I would love to meet him," Jones added. He is a busy man so he couldn't make the testimonial dinner but to have him write a piece for the brochure is a bit of a catch. I am pretty sure he is going on Saturday so it would be great to have a pint with him afterwards. I am sure he will be supporting England, but as long as he gives me a cheer if I do something good I don't mind.
