There are 14 Gilbert & Sullivan scripts (and 13 G&S scores). But there are many more works that each did with other collaborators, not to mention works they wrote without collaborators.
GSOpera is now able to support the Gilbert without Sullivan (GWOS) and the Sullivan without Gilbert (SWOG) operas in the production list. Only a few have been added to the pick list so far, but more are on their way as needed.
So if you have productions to post that include one of these shows, see if they have already been added by going to the Operas page. If the one you need is not there, use the Contact form to request what you need.
