I listened to the videos of HK and TTT.
As much as I love MM, he really does sound like a drum machine on HK. Not a fan of that at all. I hope it's just because it was the first show but the song as a whole just did not feel good to me.
As for TTT, changing the key is totally fine with me. I have perfect pitch so I noticed it right away but I don't blame them for doing this, in fact I would encourage it for James.
The jam at the end is fun and I'm glad they are doing some of this again.
However...
I'm sorry, but James sounds horrible on TTT. Especially in that one verse (understandable,) he is literally not even in the same key. I assume James improves more throughout a tour, but some of the IW songs are going to be a struggle even in a lower key.
