Wayne Rooney, still technically the team captain, missed out on the squad after a season-long struggle for form and fitness for Manchester United, handing Kane the opportunity to become the latest man to take on the armband.
Of Gareth Southgate's decision to put his squad through a Royal Marines boot camp, Strachan said: "Gareth had a look and decided he needed active rest and a bit of a laugh and a joke".
Scotland will put themselves firmly back in the mix to qualify for next summer's World Cup in Russian Federation by defeating their arch rivals, who lead qualifying Group F and are six points ahead of Gordon Strachan's men. Kane has spoken of his desire to captain the English national side and the role of leader is one he must adopt should he harbour genuine ambitions of one day winning a Ballon d'Or.
"It won't be easy and I am not being over optimistic but I think there is every chance if they can build upon that home victory against Slovenia".
It is 18 years since the Scots last overcame the auld enemy, Don Hutchison's goal securing a 1-0 win at Wembley, but Craig Gordon says his side are fully capable of bringing that wait to an end. Everyone is different and has different styles, in training, in games, around the hotel and in meetings.
Asked how Kane had reacted to the news, Southgate replied: "He was pretty chuffed (pleased). It's a great honour".
If Scotland are to lose - and the manner of defeat may be more significant than whether it happens - further pressure will surround Strachan's position. "We feel like we are as ready as ever and we're looking for three points to finish off our season nicely". England have scored only one goal in their last three away games - a run which stretches back to their thrilling 3-2 triumph over Germany in Berlin last March.
"It's what a lot of people in Scotland are desperate for us to do when I meet them as I go about". They have got great threats but we need to concentrate on ourselves.
And despite the fierce rivalry between the two countries, they will bury the hatchet "for the good of Britain".
Time for a look around!
Given the strength at England manager Gareth Southgate's disposal, McGhee believes a victory on Saturday would rank firmly among Scotland's most significant results.
Strachan also dipped out of using England striker Harry Kane talking about a potential hat-trick at Hampden as a means to fire up his players. "I think this season he's demonstrated once again why he's one of the best players in the world".
"He has had a fantastic season, finishing up top goalscorer in England, so he is another one that we have to be wary of, but they have more than one".
"He's still young and still has a lot of learning to do".
