For other videos and pics, go to Darren Criss Army and dcriss-archive.  (I actually have a hard time seeing who is there, due to it being a bit dark.  :amused )   But it sounds like they always are having wonderful guests, including as noted above, Jonathan Groff, siblings Jake and Maggie Gyllenhaal, and Tony-award-winning composer Jeanine Tesori (Fun Home).
