The September 28 Britney Spears episode of Glee may be receiving a lot of attention, but it's not the only tribute installment this show has planned for the fall.

On October 26, it will pay homage to the Rocky Horror Picture Show, a beloved 1975 film with a cult-like following. Now, E! News has confirmed that at least two cast movies from the film will make a cameo on the episode.

Barry Bostwick - who played played Brad Majors in the flick - and singer Meat Loaf will come on board Glee and portray radion station managers who have an "interesting proposal" for Sue Sylvester, sources say.

Earlier in the week, fellow original castmember Susan Sarandon said she'd be interesting in an appearance, as well. How cool would that be?!? Sound off now in our Glee forum!
