I saw a sedge warbler singing recently, I realised immediately it didnt seem to take in lots of air to produce its song, and it kept singing for well over a minute without seeming to take a breath. So how do song birds breathe to produce long periods of song?

I suspect it  breathes quickly  between notes, but you were unaware of it.

Yes, they take a series of mini breaths.
They also have 2 voice membranes at the branch to the lungs and so can sing 2 notes at once, harmonising with themselves.
