The Robin in song

I had gone to the end of the garden to put some items on the compost heap,when all of a sudden I was stopped in my tracks by the song of the beautiful Robin.BUT! I didn't have my camera with me!So I whistled to it and told it to stay.As one does? While I went back in doors to fetch my kit.
Surprise,surprise.When I returned it was still there and proceeded to serenade me long enough for me to rattle off 20-30 shots of delight!
What a welcome visitor on a terrible grey winter day?
