Am I wrong or was it once mentioned on here that Brian often sold flowers outside the gates of Downing College, Cambridge?
My girlfriend at the time was at Cambridge, and Downing was on my route from the station to her college. I'd stop to buy her flowers from there each time I visited - when the stall was open - because it meant I didn't have to venture into the market or Sainsburys on Sidney St.
Apologies if I'm misremembering, but if not, I may have met Brian a dozen times without even realising.
