that's what i said maybe i wasn't clear! if he tries to make the key change at the chorus at the tlfr version it would still be too high for him right now, what i was saying was to take this version which is a little less "epic" and more intimate, lower down the verses and have a lowered down version of the original chorus so that he could still have that key change at the chorus... idk if i made myself clear but i'm not an english mother-tongue so it's pretty hard for me
however what i cannot understand is how a 30 years old band like this does nothing to improve this situation!
