Why not take over a tavern? 20 or 30 lusty voices joined in chanties would be enough to dominate a place like Gritty's and as long as we are buying food and drink they wouldn't dare do anything about the music. If we get there early enough we should be able to fully take over an area without too much encroachment from the non musical patrons.

Tom and his crew manage to do it every Friday at the Press Room. Tom gets there at 4:00 and occupies the central table and the others filter in through the next hour or so.

Just a thought...
