For the first ever US Red Nose Day on NBC, all the stops were pulled out. What happens when you combine Chris Martin, Liam Neeson, and a large section of the cast of 'Game of Thrones'? Well, you get a behind-the-scenes mockumentary of 'Game of Thrones: The Musical', featuring some of your favourite characters singing such hits as 'Rastafarian Targaryen'.

The six-minute sketch contained a lot of the current (surviving) cast of the show, like Peter Dinklage, Emilia Clarke, Nikolaj Coster-Waldau and Kit Harington, as well as actors like John Bradley (Samwell Tarly), Alfie Allen (Theon Greyjoy/Reek), Iwan Rheon (Ramsey Bolton) and Charlotte Hope (Myranda). There was also an appearance from some of the long-past actors like Mark Addy (King Robert Baratheon in Season One), Thomas Brodie-Sangster (Jojen Reed) and Rose Leslie (Ygritte), who received a serenade from Kit Harington. Diana Rigg (Olenna Tyrell) also made a brief appearance to discuss how the whole concert was a terrible idea.

The songs in the sketch were particularly well made, with a hilarious ensemble piece about the infamous 'Red Wedding', and Kit Harrington's cover of The Troggs' 'Wild Thing' - here sang as 'Wildling (You Make My Heart Sing)', while Peter Dinklage's big number about his character still being alive despite people like Sean Bean having their character's killed off early on. The whole thing was incredibly knowing, and played well into the tropes and catch-phrases of the show. Rose Leslie's "You know nothing, Chris Martin" was particularly well-suited.

All-in-all, the piece was very well put together, with a great narration from Liam Neeson - leading to a nice final gag in the same tongue-in-cheek nature of the same vein as the rest of the piece. With sketches this impressive, and talent this good, it seems like the US and Red Noes Day are a brilliant fit.
