It was only a two-year absence: 2005 and 2006. (Yes, 2007 - 2004 is 3, but they played until the end of 2004, and played again at just into 2007, so 2005 and 2006 were the only years they weren't playing as a group.) Aloha, Brad The detail is incredible however we are missing the equations. Don't forget to include the math that explains the result.
