Sorry, just got distracted there by the thought of Suibhne's Bellamy tape.

What I wanted to say was in reply to CS, about the 'bleat'. I think my introduction to Bellamy solo was the song "the London Waterman", which he does magnificently but... um... it's a bit... y'know... raucous, and, er... bleaty. Some time later I came across the song again, this time sung by June Tabor, and immediately had to learn it. Once I'd got the words and the tune off I started really listening to how the song sounded when I was singing it; I knew I wanted to do something different from June Tabor's version, which is very nice but a bit too pretty, and that meant being a bit declamatory here and a bit more emphatic there... At that point a lightbulb went off - so that was what Bellamy was doing!

This doesn't explain the actual tremolo, I have to admit, and that does get in the way when you're not used to it. But I think it was all part of his way of getting a performance out of every song.
