Ahead of the show's premiere after the forthcoming Super Bowl on February 6, the full version of the 'Glee' cast's 'Thriller' and 'Heads Will Roll' mash up has surfaced. 

At 3.37 minutes long, it's a fast paced fusion of Michael Jackson's classic hit and equally spooky  'Heads Will Roll' by the Yeah Yeah Yeah's.

The episode it will feature in, entitled 'The Sue Sylvester Bowl Shuffle', is set to include other top songs such as 'California Gurls' by Katy Perry, 'Need You Now' by Lady Antebellum and 'Bills, Bills, Bills' by Destiny's Child.
