I'll admit to enjoying a bit of a sing song and I can sing song a little bit in my own inimitable style but I get to that bit in the Nilsson one where it's "I CAN'T LIIIIIIIIIIIIIIIVVVVVVVVVVVVVEEEEEEEE" my voice breaks on that each and every damn time, he's probably the best singer ever, so very emotive with it too...
Hasn't he got 4 octaves which is like half an octave more than Freddie Mercury and Paul McDougal? I'm not proficient in such technical matters, I think I heard that once though...
Would not be surprised at all.
