It may be bad form to "pile on" once a point has already been made, but I'm going to chide Bill D anyway for coming down so hard on Chico, who is not only a relatively new member, but who has made MANY contributions of songs, almost always including chords.

Older American Tin-Pan-Alley songs like "Tootsie," not unlike British "music hall" songs, can certainly be a legitimate part of a singer's "folk" repertoire, especially someone with a bent towards ragtime, which is certainly a time-honored subgenre of "folk" guitar fingerpicking.
