Good to hear Mark Hopwood on Broadcasting House on BBC» Radio 4 this morning demonstrating the use of the ACME Thunderer whistle. Blowing of whistles has been suspended during the Covid-19 crisis to reduce risk of spread of infection and Mark explains the use of the whistle - in more normal times - to host Paddy O'Connell.
It'll be on BBC Sounds later: I'll try and remember to come back and post a link. It's around 27 minutes into the programme.
Didn't know he was a referee?
