What you noticed is partly compareable to what I posted in a nother thread:

1. Last man standing: This song is usually written in Em, the way Jon could sing it on the TLFR DVD too. BUT WHY did the play it in C#m yesterday, 3 notes deeper as usual!!??? This just sounds damn boring!! Even Tico could have sung it yesterday. There's no need for that Jon!

2. Prayer: Oh my god, there was no way Jon could sing the lower parts of the chorus after the solo! Weak and frustrating...

3. Have a nice day: Suddenly Jon had a stronger voice. Best performance of that song for me so far. Why not such engagement and power in all songs Jon?

4. Radio: It did and will always suck with singing 1 octave deeper as usual! Why not playing in D or C instead of E, so Jon's voice would be a big higher? I mean, when they play Living in sin, they dont play in E and Jon sings 1 octave deeper. No, the play it in C, and that sounds ok

5. Who says...: Should be next single, works great live as its a fun song like saturday night. Jon seemed to have fun singing it too...

6. Raise: Still great rocker, hopefully a part of the next tour.

7. Bad medicine/sleep dead: Remove it from the setlist! I'm fed up with those, and I think many are...
