Craig Ferguson's music video for Scotland trip

Craig Ferguson will be taking "The Late Late Show" to Scotland mid-May, and as everyone pretty much knows, you can't even begin to take a late show to Scotland without first  producing a music video...which Craig has done. Here it is, featuring the Glaswegian band , The Imagineers, and see if you can guess who the special guest stars are. (OK, you're not in the mood for guesswork: Mila Kunis, Michael Clarke Duncan, Rashida Jones, David Sedaris and Ariel Tweto...David Sedaris??!!)
