You may have thought that George Lucas would want the infamous 1978 Star Wars Christmas Special – a generally embarrassing music, comedy and dance “spectacular” produced for CBS TV in 1978 – to be buried, forgotten and banished from YouTube (uploaded from dodgy sixth generation VHS copies), but apparently not. Because presumably somebody at Lucasfilm has given the thumbs up for Glee to resurrect it for this year’s Christmas special.

“We’re doing a Christmas special within the episode of Glee and it’s a throwback and a tribute to the Star Wars holiday special and the Judy Garland Christmas special.”
