I'd worked it out and done my own research, Chris.
When Saturday Comes: The Half Decent Football Book starts their description of the team as "Leicester have spent much of their unremarkable existence bouncing between the top two divisions - never quite producing a side good enough to win major honours, yet never quite sliding down to the third tier."
Well known players (mainly for other teams) that I can find include Gordon Banks (England), Keith Weller, Frank Worthington, Gary Lineker (England, Everton, Barcelona, Tottenham), Allan Clarke (Leeds), Peter Shilton (Forest, Southampton, England), Alan Smith (Arsenal), Alan Birchenall (half-time raffle man).
