But some i know that went to see the I&W&B show said that JLB looked fedup and not as enthusiastic as he has been in the past...
There have been 14 shows on the U.S. leg of the I&W&B tour so far. I have no idea what "some" people on Facebook might have said, but I haven't seen any such comments and, based on my attendance at the Los Angeles show, I would disagree with this sentiment.
it concerns me for DT's future.
Why do you care what a bunch of folks are saying on Facebook?
Especially now that they are taking a break.
They always take breaks at the ends of tours.
Is this one of the causes? Are they giving him time to rest?
I'm sure James will have as much time as he needs to rest his voice. I also think you're making way too much about stuff you read on Facebook.
Is anyone else concerned about this and perhaps reckon he should hang up his boots for DT's sake?
I'm not any more or less concerned about James's voice than I have been for the last 10-15 years.
Obviously voices change with age but thats not what worries me. Is James getting fed up and bored?
No one here knows. You can tweet and ask him or post on one of the message boards on his web site.
Look...as time passes, it becomes more difficult for James to deal with some of the material (especially from the early days of the band's career). He has started changing the vocal melodies on some songs to make it easier for him to sing. Whether he's "fed up" (with what?) or "bored" is something none of us will ever know unless he announces it publicly. Until then don't worry about things that are completely outside your control.
