The Paisley side sealed a Scottish League Cup final meeting with Hearts and ended their nine-game goalless run against the Bhoys with a 3-2 victory on Sunday afternoon
The Paisley outfit claimed a historic 3-2 victory over SPL leaders Celtic on Sunday afternoon, despite coming into the game having failed to score against the Parkhead club on nine straight occasions.
But, after goals from Esmael Goncalves, Paul McGowan and Stephen Thompson helped put the Buddies in the final, Lennon revealed that his players had called on an unusual source of inspiration prior to the game.
“We were inspired by previous St Mirren - Celtic games, way back to ’59, we watched them on video having some monumental results," he told reporters.
"The message behind that was to fuel the players with belief in the working week that it can be done, and when you fuel them and they buy into it as much as that, it brings their strengths and qualities out.
“What had inspired me was that a fan had put a lovely montage on YouTube and somebody showed me it prior to the Ross County game.
"I had a look at it and it went away back to ’59 and to ’89 where they had some great results against Celtic and leading up to the result they had in 2009.
“When you come up to these games you’ll try something different and they didn’t let us down, it was a fantastic effort from everyone."
The 43-year-old went on to hail St Mirren's fans, who were in fine voice throughout the showpiece game at Hampden Park.
"I’m absolutely delighted for the fans that we can bring another piece of history to this wonderful football club," he added.
“I thought the full 5,000 of them today were terrific, you could hear them continuously throughout the game and hopefully we can start to see them come out at Paisley on a regular basis, I know money is tight, but that’s a thank you to them.”
The Whitburn-born boss understandably had further praise for his players, but refused to single out loanee striker Goncalves.
“Absolutely terrific, I don’t want to single anyone out," he said of the performance.
"But the biggest part today was the boys that had to miss out, everyone’s had a part to play and this season isn’t about today’s game, it’s about the full group.
“We had no hesitation after seeing [Goncalves] for two days, he’s a very confident lad and he backs that up with the terrific ability he has.”
