As I said, I'm aware of different breathing techiniques and exercises (I used to get a "Musician's Channel" that looked at them), and I've heard someone do the whole tune as an into. to Greensleeves (as I do), on an oboe, ON ONE BREATH; and I've heard others breathe during lines. However, I stand by my traditional one-breath-per-line phrasing.
Also, I only have the cheapest Argos digital camera, and therefore can only record a video without sound - however, on either myspace or youtube, you may like to view another breathing-type exercise I do: i.e., going through a 2-octave chromatic-scale on the tenor-recorder/English-flute, which takes about 40 seconds, on one breath.
