@georgeb georgeb, are you still a union player after all these years?
No, Doc, when I quit playing in 1965 I dedicated myself to climbing the ladder of success in the printing and publishing business to give a good life to my wife a 3 sons, and it was the right move at the time. I started out in that business in a daily newspaper as a proof runner, then an advertising salesman and finally into management. I retired at the close of 2000 as general manager, publisher and vice president at one of eastern Canada's largest printing and publishing operations. I never touched a horn again until 2016 and I no longer play for money, so I had no need for the musicians union. But they were sure a great help to me when me and my band were members.

Welcome to TB! I admire your indomitable spirit, and your unquenchable thirst for music. Feel free to ask any question you might want answered, even if the question sounds stupid to your ears - there is a saying in Vienna, "You can only get cleverer by asking stupid questions."
As to holding the instrument: ErgoBrass have a very nice contraption that might suit your needs.
