The Parkhead club is celebrating the 20th anniversary of McCann's 11th-hour rescue which saved Celtic from financial meltdown.
And last night it was revealed the Scottish-born Canadian and lifelong fan will be back at Celtic Park next season - to unfurl the SPFL Premier League flag.
In an address to the Celtic fans on Saturday before the game with Inverness, Quinn paid his own idiosyncratic tribute to McCann - by adopting a trademark flat cap.
Quinn jumped at the chance to join the revolution when he became a non-executive Director and vice-chairman of the plc board in March of 1996. He later became chairman. He said: "It's difficult to exaggerate the impact that Fergus had. He transformed the club from one that was behind the game to a club that was up for the game and looking ahead all the time."
He continued: "Among all the achievements that Fergus brought to Celtic, I'd say that possibly the biggest was the share issue.
"The share issue gave the supporters the chance to be a tangible part of the club and the ground was built by the supporters so they felt like this was their stadium.
"The club is now one of the best-run clubs in in Europe. It's efficient, properly managed financially, it's got a forward plan that looks beyond the current season ahead and it has a long-term view as to where the club wants to go."
