Shaw Taylor is today best known for presenting Police 5, a long-running 5-minute television programme first broadcast in 1962 that appealed to the public to help solve crimes.
He later presented a spin-off show for younger viewers called Junior Police 5, aka JP5.
His catchphrase was "Keep 'em peeled!" - asking viewers to be vigilant.
This was originally used at the end of every JP5 programme, but according to Shaw Taylor himself, "...at the suggestion of a friend I tried it out on the adult Police 5. I thought it sounded a bit naff at first but then the studio crew seemed to get withdrawal symptoms if I didn't say it at the end of the programme and it became a catchphrase that complete strangers still shout at me in the street".
