I think you have to be quite young to have an idol and like Leefer it was the Don for me.
He could win any match by scoring from anywhere single handed and he could do this against any team, witness West Ham, Liverpool, Arsenal and so on.
It was no surprise he could do the same in the top league when he eventually joined the Palace. He missed the first 2 or 3 months but could otherwise have been the player of the season that year.
However his bad hip and relegation for the Palace in spite of Don's best efforts meant that Town enjoyed nearly all of his best days. Rarely do you see such extravagant talents in so modest an individual.
Kammy was a slightly later hero - enduring monkey chants from Pompey fans whom he had left for the Town on his first game against Pompey and pretty much ending his Town career I think (Reg will correct me) by responding to racist taunts by breaking the Shrew's Jim Melrose's nose at the end of 90 minutes at Gay Meadow .... and picking up an ABH for his trouble.
In between his sliding tackles were as mesmerising as Hendrix with his guitar (well maybe not quite)
Chris Kamara was my first Swindon idol. I remember the diving header against Pompey in the late 70's in the 3-1 win (I believe). Coming from a Pompey father I could have taken the "blue" road instead of the "red"
I recall writing "we've got Kamara - STFC" on a wall in Portsmouth and later remember that great diving header.
I also recall the Pompey fans after the game on Swindon Station and my scarf being well hidden whilst boarding the train back home. Now they were some nutters.
As for slide tackling Kammy was a genious.
