Hmm. that means that a lot of people want to hear the Jim Ketch Swingtet playing '30s-'40s small group swing era tunes . Or, what this likely means is that there are enough jazz fans around to go to both performances.
I'll know more tonight after I catch the first Sharp Nine set & then the 10p Calderazzo-Revis set. I'm optimistic; I think it indicates that the jazz audience has grown here to the point where these two events are successful.
