Everyone's personal grieving time is different. Some of us hurt longer than others when someone truly amazing has passed. And yes, I'm sure they still miss him too, since it was last month they lost him
and this fan is still feeling the hurt. And he will indeed always be missed.
It's much too early to move on...and I don't know if ones that knew and loved Jerry would put it that way, anyway...but I'm sure they'll strive to do performances he'd be proud of.
There may come a day when they simply live on in video, and that's not necessarily a bad thing. Even when they stop one day, they will live on, performed by Jim's crew, on video forever...and the performers will live on in our hearts...
