Andy Catto, from Petersfield, makes the trip up to London every Monday as he has been a guide at St Paul's Cathedral for the last two years or so.
On Wednesday 18 March he spoke at two meetings here - the U3A and the Area Historical Society - about St Paul's.
He told us his talks go further than the tour with photos and stories about the Cathedral and its history.
He spoke to Mike Waddington about his experiences, about Royal Peculiars and where the phrase 'robbing Peter to pay Paul' comes from.
