Basically whatever some people think there are still people who enjoy the band,no matter of Jons voice being on the edge.
And one thing also,people make mistakes by compare them to other bands,that is not possible.Like,look at U2 or look at Stones,or Springsteen etc. Why? There are no same bands,not by songs,not by playing and specially not by singing.
Our boys have singles and songs that are very high to sing,that is not exuse for Jon but their songs are pretty high from old ones to new ones and those are hits need to be play.
