Stumbled across this, that may be of interest to anyone on the East Coast of the U.S. - a one-man performance of Call of Cthulhu by David Nielsen on 25th May, 2014 - http://www.westchestergeeks.com/geek-pride-day.html
It looks like David also does Cthulhu parties! http://neilsenparty.com/cthulhu.html
Note: I don't have any affiliation with David Neilsen, Westchester Geeks, or even the USA for that matter.
