The hourlong “Weird” Al Yankovic special is coming around the corner when she comes, which is this Saturday, Oct. 1, on Comedy Central. “Weird Al” Yankovic Live! – The Alpocalypse Tour is his first TV special since 1999?!?

So roll out the barrels of preview videos. This animated ditty, “Polka Face,” is actually a medley of accordion-driven versions of songs by Justin Bieber, Ke$ha, Britney Spears, P!nk, Lady Antebellum, Katy Perry and of course, Lady Gaga. Roll the clip!

Here is his send-up of Miley Cyrus with “Party in the CIA.”

And here is Green Day gone north of the border with “Canadian Idiot.”
