Fantastic days eh Michael,the man credited with bringing Big Jock to Celtic was Jimmy Gribbben from Baillieston, where I grew up. Jimmy was a scout at Celtic and their first and second choice centre halfs were out injured. Jimmy remembered Jock played C.Half with Albion Rovers and was now in Wales and told Bob Kelly that Jock would be an ideal stop gap till the injured players returned.The rest is History.On that Great Season,my mates and I sat on the Rickety Pie Stall Roof watching Celtic hammer Man Utd with their star players such as Charlton, Law,Stiles,Stepney and Giles all playing and getting roasted by a swashbuckling Celtic. (Utd won the European Cup the following season).I attended the game in which the Lions played their last game together, Ronnie Simpson led out the Bhoys but didn't play as he sustained a shoulder injury when colliding with Jimmy Quinn, a young prospect with Celtic and on loan to Clyde. This injury ended Ronnie's career. What a keeper he was.
