a good trick to practice is making sounds when breathing in - most people can inhale and still produce some vowel sounds. I think 'O' is easiest.

If you are running out of air rather than overinhaling you can then snatch a little breath to get you to the next natural pause without there being a silence.

I can breath in and sing 'its''you''my' or 'and' - I don't try to do this for a deep breath, the sound is more nasal than my normal voice, but it might account for the problems people have in singing with me. It is something I just do - I never thought about it until other singers asked me when I breathed.

I do have a lung capacity rather larger than the expected volume, I assume from singing a lot, but breathing during a song is not something I have ever needed to worry about, what with remembering the words and the chords I leave everything else to the automatic systems.
