The harmonies are the one thing that I think sets FP out from the rest, their voices blend in very well together. I assume that is in part to Matthew and Aaron, especially as they haven't taken a lead vocal (yet). Hope's harmonies this week were all backing singers, that much was obvious, I couldn't hear backing singers with FP (if there even was any).
I hope they realise that they should stick to what they're good at, keep the distinctive singers up front and use the harmonies to best effect by not separating all the voices out so obviously.
I don't like it when I can tell EXACTLY who is singing which harmony, it should be blended together properly so you can't make the distinction.
Anyway, thats me for the night, have fun fellow FP fans. G'night!
