It's lovely to see these sentiments but such a shame that there is the need for them.
Watford are my first footballing love, though being in plymouth I rarely get to see them and therefore follow the Green Army far more on a day by day basis.
I started to follow Watford in about 1981 in the old Second Division (didn't make the 84 cup semi or final sadly) but had many great years of enjoyment during both GTs spells in charge - coming second to Liverpool and Wembley in 99 stand out.
Was lucky enough to meet him a couple of times and he was both very charming and knowledgeable.
I believe his legacy will be the total transformation of the experience of watching football from the hooligan days into a far more family friendly experience (though not the corporate prawn sandwich munching part). He, Sir Elton John and the WFC board of the early 80s introduced the family terrace (and later seated family area) and kickstarted much of the community work that is taken for granted these days.
I was going to the Stevenage game but will be at Vicarage Rd instead tomorrow- I just had to be there! It really feels like I've lost a family member.
RIP Graham
