yeah i think when Will gets on stage he has a lot of energy and adrelnaline going thru him so thats gonna come out in his voice too, i think he's great live tho.
Did any1 notice tho at the performance of summertime in London, he started summertime and got every1 to join in, then i think he missed his queue to start rappin, and he turned around to Jeff and said, hold on we need to do this again and made the crowd as an excuse. It might not be but thats just what i think, he did a good way of gettin around it tho.
