I remember Theo as a very young kid growing up in Newhaven; I presume its the same person. I didn’t know him, just knew of him; due to his dress sense he stood out as a stylish and cool character. He was a few years older than me, must be nudging 60 now?
Thinking about it now, what on earth compelled the announcer to tell this joke? As @smillie's garden said, it’s not as though half time jokes were a thing; quite the opposite.
I was quite young at the time and all these years later, because it was so surreal, embarrassing and out of character for a PA announcement, I have sometimes wondered if I imagined it …..even though I remember it so clearly.
