How Can I Keep From Singing?

Needs to be seen on largest option.The title has capitals because I'm quoting the title of a hymn. I saw this robin on the aerial this morning (please see 5th May, main album for another aerial shot) and took a picture for the fun of it. Then I got it on the computer and saw the bird's beak open in song, thought of the hymn, how I feel about singing, and decided to upload the photo for the joy of it. Cropped, nothing else.
