Looks like we didn't do an "on this day" for May 23rd, so here goes.
Wrestling overseas, on this day, Bert Assirati beat big George Gordienko (wrestling as "Flash Gordon"), in Mumbai, India, on this day in 1953.
On our TV screens, on this day in 1970: -
Jon Cortez (1) v Julien Morice (0)
Pat Roach (W) v Ray Hunter
Brian Maxine (1) v Ted Heath (0)
The matches at the bottom of the bill could have easily been top of the bill
