Blackbird and robin duet on mid-summer's day

I spent a whole wonderful day in the garden on Friday and several hours on Saturday and Sunday day but I still haven't quite caught up!   Everything is growing like mad and some heavy rain showers are battering the flowers but at least preventing the need for watering.   The late spring has brought an unusual combination of things into bloom and I was surprised to hear the rather comical gurgling-chuckling calls of a fledgling blackbird still attended by its father.   Later on in the evening a male blackbird settled himself on the bay hedge beside rosa Madame Alfred Carriere and entered into what seemed like a wonderful duet alternating his song with a nearby robin, something I have never before heard.
Here he is casting a beady eye on me!
