Before my time, but guys like Eddie Turnbull, Jim Baxter and Jinky Johnstone of course all played at FP.
Not quite in the legendary status, but when I moved down to England in 1988, I used to be able to tell my mates how I watched guys like Steve Nichol play with Ayr Utd, Alan Hansen with Partick, Andy Gray with Dundee Utd, Stevie Clarke with St. Midden, Nevin with Clyde etc. before they made their big moves south.
Can you imagine someone from Ayr Utd getting transferred to Liverpool these days?
