Non-falsetto notes
Some of the songs are tuned down half a step, hence the reason "If God Will..." is a B instead of C.
Bad C#
Who's gonna Ride, Red Hill, Angel Of Harlem, One Tree Hill C
Pride, If God Will..., Vertigo B
Still Haven't, Hawkmoon, Like A Song, Last Night on Earth Bb
Miss Sarajevo, Stay G#
There are lots of songs that hit an A, such as "Sometimes", "Sort Of Homecoming", "Even Better", and most of the songs from the last 2 albums in fact.
the "COLD man" part in Wire is actually a D which makes it the highest non-falsetto note so far, I believe.
I own "U2 - The Complete Songs" which has all their songs up until 1998 with the vocals tabulated.
Try singing along to "Like A Song" with all those A's and B's, VERY hard to do, even tuned down half a step.
Hitting a high note is one thing but maintaining it for a few seconds is even harder. Listen to the end of "A Sort Of Homecoming" where Bono holds that A note for like 7-8 seconds.
Then you have the middle 8 in "Native Son" which I think is an elongated B note.
