Thanks for the welcome (that was my first post).
I saw the Warblers open for J a couple of years ago in Amherst, and they were great. They’ve also done some shows with him in Boston (I think) and maybe New Hampshire and Rhode Island.
I know the article you referred to. Watt also said some nice things about the Warblers on his website — something about "frosty" (and someone had to explain to me what that meant).
