The original version of the performance, which aired last November, is available on YouTube and has been seen over 22 million times since it was posted and is the second most-viewed video on the official "Glee" channel. Searches for "Glee" on YouTube have continued to climb in the past year, hitting their peak in May. In 2010, the top rising "Glee"-related search was for the "Teenage Dream" performance.
At posting, the "Mini Warbler," who performs the full choreography from the original, still has a small number of views, but it will be interesting to see where it goes from here given the popularity of the original and the show's growing fan-base:
Update: A little attention from Darren Criss, the original Warbler himself, doesn't hurt either.
