For 25 years Cornelius Lysaght was Mister Horse Racing for BBC Radio - broadcasting live into  the daily and sports programmes of BBC Radio 5 Live and BBC Radio 4. Whether over the jumps or on the flat, his voice has become synonymous with the sound of thundering hooves on turf. But what does it take to be a specialist in such a global and historically rich sport? And just how do you manage all those bizarre horses names? And why did Reggie Bosanquet put him off drinking gin forever? In conversation with the Original UK Voice of Siri - broadcaster Jon Briggs.

Cornelius (@CorneliusRacing) can be heard regularly on his own podcast Corneliuscast and writing regularly for sporting journals. www.corneliusracing.com
