Who remembers whistles, the scurge of many an allnighter and alldayer in the 70's. Mind you had to have the right one , a ref's type, no good having one of those police types
Also dark glasses at 70's allnighters very cool , I tried it once but it only lasted half an hour, fell over so many bags and people trying to sleep that I gave it up.
And lastly Guy & Keb et'all and the one black glove.
