Hi,
This is the closest I an find to a schedule, from Steve Soares' website:
Jelly Rolls a dueling pianos experience.
Classic sing-along and good times await guests at the hottest dueling piano bar on the waterfront, featuring non-stop live entertainment in a rowdy, warehouse atmosphere.
Open at 7:00pm, shows from 8:00pm to 2:00am. $5 cover, bar.
