"It was like watching a heavyweight boxer against a middleweight".
Hart was slated for his contribution to Leigh Griffiths' double free-kick, as well as a moment of madness that involved a back-pass.
England substitute Alex Oxlade-Chamberlain opened the scoring just a few minutes after coming on for Gareth Southgate's side, but the Three Lions were stunned by two late free kick from Griffiths, who struck twice from nearly identical positions to put Scotland in front, only for Tottenham striker Harry Kane to score in injury time to deny the hosts a famous victory. "Sometimes in global football, surprises happen and that was nearly the case at Hampden".
"Then, most importantly for me, heading into injury-time 2-1 down, I don't see anyone sink to their knees, I don't see anyone hit the floor".
"To get the goal was special".
He added: "We said we had to expect the unexpected".
"When we went 2-1 down, a few lads could have been on their knees or had their heads in their hands". That's what we've got to show.
"Obviously I was wearing the armband today but I think we've got a lot of leaders in the team".
The Scots sensed the win was there for the taking and when Livermore brought down Chris Martin in a similar position to where the first goal was scored from, Griffiths again stepped forward.

Twelve million people in the country were forced to abandon their homes in 2016 - that's more than half of the country's population.
"But they stuck their chests out, walked back to the centre circle and said "Let's get something from it".
Kane claimed England were aware of the threat Leigh Griffiths posed from set pieces, although his initial description of the Celtic striker as "their lad up front" perhaps suggested otherwise.
"But we are identifying those areas and we'll keep working on it".
Close. Still, a Scotland vs England clash that will stay in the memory for quite some time.
"On our day we can match any-body".
England looked more risky on the rare occasions they got their opponents turning and Kane had another half chance, with Craig Gordon stranded after coming out of box to head away a long ball.
"But one lapse of concentration has cost us in the end and instead of getting three points we got one".
The first proper chance came on 17 minutes when Kane - skippering England for the first time - beat the offside trap with lovely control inside Kieran Tierney, but blasted a left-footed half volley over the bar.
"It was fantastic", said Kane of the team's character, which was praised by Three Lions chief Gareth Southgate.
"The first free-kick is careless, the second free-kick is a slip, so I'm not sure there's a lot we could have done about that".
"I thought we came into a hostile atmosphere and controlled the game completely, we should have been further ahead, but if you don't get the second goal, you run the risk of an equaliser at any point". "I have felt it important to give people the opportunity to lead in different ways".
