Echoes in brackets in Vertigo

[Ugo1970]

I've noticed that, in the last two sequences, Bono's eighth "yeah", the one 'sung' only by the echo, is bracketed. [(yeah)] In  the same style, I think that the very beginning  of the song should be like this:

Uno (uno), dos (dos), tres (tres), catorce (-torce)

;-)

[Carl]

There comes a point where sacrifices have to be made to make things readable.

I mainly did that because one of the remixes just had the 7 "real" yeahs and not the "fake" one inserted to be the 8th.  It doesn't sound quite like an echo, more like something sung on top of the original seven.
