With age comes circumspection. Sometimes.
'So a couple of years ago,' says Greg Dyke, well into our chat and leaning over, almost conspiratorially, 'I went cycling with my old mates for my 65th birthday. Six of us, all been at school together in Hayes and as teenagers we'd cycled round Devon and Cornwall, staying in youth hostels.'
He wants to do the same ride again so he has the T-shirts printed - '50 years on' - and sorts out the same hostels and raises sponsorship for the tour and cracks jokes about how hopeless they were, never even managing to find any girlfriends for the original trip.
