Rhiannon was crazy good! How can so many of the yogscast sing these days? It used to just be Hannah, and she isn't nearly as good as a lot of these newcomers ^^
This was so entertaining, but I sadly don't know either of them. I may have heard Craig's name, but I will need a "best known for" for them. Or how they are related to the Yogscast or each other.
Craig is best known for being the editor for Hat Films. He edits almost all of their videos and has been in multiple videos of theirs too. Rhiannon is best known for being part of High Rollers D&D she plays Sentry in their current campaign Aerois. Also in terms of how they relate to eachother well Craig and Rhiannon are engaged. Hope that helps :)
