Waller is my most absolute adored showman/ musician of all time. Some three years ago I put together a cabaret show with a load of his best compositions, most of which were left uncovered by the Broadway revue. There is some absolutely marvelous material--songs like "This is so nice, it must be illegal," "You're only slightly less than wonderful," and "More than Satisfied" that only collectors could show me the way to. That stuff has just sat in the LOC and collected dust. How fortunate for you to have one of Fats' rolls (?) Odd that Williams is attributed with authorship though. I thought it was a Porter Grainger tune.
