I had a few brews with Jaco when I was 20. I remember that trying to connect was strange for the first beer, for a few reasons. I made a point of not asking him a bunch of music questions, which he noticed and seemed to appreciate. At some point though I mentioned his work with Joni Mitchell, and asked him a non-musical question about the experience, and it was only then that the dynamic changed, and he smiled big at me, before sharing.
