It is actually "Top of the World" by the Carpenters.

This was taken from a pure vocal track - there isn't even audible bleed 
from other tracks let alone any instruments playing.

I suspect a large part of what is going on is that waon is being fooled 
by vibrato - it sees a change in pitch and assumes this is a deliberate 
move onto another note.

I had a look at the options to see if there was any way to specify how 
far the frequency has to change before it is seen as a transition or 
whether I can specify the tempo or minimum length value but I can't see 
how to do that.
