Hoopoe singing in the rain?

On Thursday 14th May, at 6.39am the ever dependable Andrew E. posted that the Hoopoe was singing from the rooftops but it was cheucking down with rain where we were barely a mile away! When the rain stopped not long afterwards I drove over 7.40- 8.05am, as I walked down Mutford Drive I could hear the Hoopoe singing 'hoopoo-poo...hoopo-poo' but I couldn't see it so I walked to the end of Lakeland Drive, no sign there either, walking back to Mutford Drive just before 8am I heard it again calling just west of the end of Mutford Drive. I scanned across and on the aerial I immediately saw the fantastic Hoopoe perched on an aerial, it later flew onto the roof, perched here for a minute or so before a movement in the garden of the end house it flew east and out of sight. Later, on as I arrived home from work a House Martin was flying low over our front garden.
