Cap'n; as much as I have admired the Lewes programme of workshops (from afar unfortunately) I see little there that resembles anything ongoing for beginners - not saying there isn't anything, just that it doesn't appear appear on that list.
A number of clubs we have been involved with have had long running workshops specifically planned so they could cater for non or new singers who wanted a start. Some of these have proved pretty successful over the years.
They were structured in such a way that they could be diverted into other channels for the rest of us when there were no newbies around. The London Singers Workshop, which existed in parallel to at least three clubs we helped organise, ran for nearly twenty years; we set up a magnificent sound archive, and a reasonable library for the use of its members, which proved invaluable - (wonder where the Bronson is now?)
I have been giving the subject of teaching some thought lately as it keeps cropping up over here.
While I believe that singing can be learned, I'm not sure it can be taught, at least not without creating insurmountable problems.
Maybe the subject for a separate thread once the season to be inebriated is over?
