I think that's a fine idea. It would, of course, mean that some would move between workshops and miss parts, and thus might try to sing the 4th version of "Young Hunting" in 30 minutes... *grin*...but we could deal with that.

Ballads are a special case due to the length of some and the predictable discussions and comparing versions, so I quite agree that a longer time period in a dedicated space would be nice.
