(in the above post, NYT Palace Theater review, third article down). Omigod, does that describe him to a "T." I'm ROFL*. See the restored 1928 Blossom Seeley and Benny Fields Vitaphone short (first song: "Hello, Bluebird") for an apt example of his accordionic pipes.

*not a cryptic reference to B. A. Rolfe. "Rolling On the Floor Laughing."
