Tom,
Thank you for sharing this news on this forum, and my sincere condolences to you and your family on the loss of your brother.
I don't think I need to write about who Jim was on this forum- his posts show someone who was passionate about this music, and completely over-the-top (in a good way)with his enthusiasm for it. He loved his life, he loved music, he loved his family, and he especially loved being a grandfather.
As a musician, i tend to remember- and remember fondly- those people I've met who have encouraged me in my music. I can think of VERY few people who have encouraged me in my music more than Jim; whether in person or through e-mail, his positive outlook and kind words were unstoppable. I remember him being at concerts I played in PA, and although he probably didn't like everything I played in those evenings, he was always there after the show with a big hug, a pat on the back, and encouraging words about my music.
He will be missed, and he will be remembered.
Jeff
