I think the songs live lack the emotion of say 10 years ago - nothing better to get the crowd going carzy is for the lead singer to sings his guts out. But Jon is very much in the comfort zone for me when he sings live now.
Have loved the band since SWW and have heard his voice deterioate over the years but thats the case with most singers. Doesnt mean they cant put on a good show but means tough new songs IMO to sing like I AM and BELLS OF FREEDOM may not get played on the new tour , along with ALWAYS , DRY COUNTY etc. etc.
They to me lack the energy on stage as well. I remember Wembley Jon and Richie were running the length of a vey long stage , backwards and forwards during a song !! Wont see that nowadays - but they are getting on !
