Weird Al Yankovic joins Weezer on accordion for their cover of Toto's 'Africa': Watch

After caving in to a viral online campaign earlier this May, Weezer's cover of Toto's 1982 hit 'Africa' has suddenly become their biggest hit in over a decade.

Earlier this May, the music world experienced first hand the strange benevolent power of the internet in bringing memes to life. After a viral campaign on Twitter by a super-fan that relentlessly requested Weezer to cover Toto's 1982 classic hit 'Africa', Weezer finally caved in and obliged. The LA-based alt-rockers' kitschy cover was always built to be an immediate viral sensation, and that’s exactly what it was. It kicked up a storm on the internet, starting a whole saga as the track quickly climbed the charts to become Weezer's biggest hit in years!

Soon after the cover, Toto returned the favor by covering Weezer’s 'Hash Pipe.' “We figured since we were smoking hash since before they were born, that’s the one we should do,” guitarist Steve Lukather told the audience in Vancouver where they debuted the cover. “This is our tribute to Weezer. God bless ’em.”

Not only is the Internet fan-fiction of a cover Weezer's biggest hit in nearly a decade, but they keep finding ways to make it even better. Last month, Weezer was joined by Toto keyboardist Steve Porcaro as they played the song on Jimmy Kimmel Live!. Now, adding even more flair to the viral sensation, it looks like other kings of nerd-rock comedy are joining the party.

On Wednesday night, Weezer played the Forum in Los Angeles, where they obviously busted out their cover of 'Africa'. But they had some special help for their performance.  Mid-way into the performance, Weezer frontman Rivers Cuomo exclaimed, "Ladies and gentlemen, please welcome ‘Weird Al’ Yankovic!"

The crowd could barely contain its excitement as the iconic comedy-rock legend came out with a serious look in hand, equipped with an accordion of all things, to complement Cuomo's guitar work. Weir Al belted out the epic keyboard solo of the song on his accordion before stopping to add a quick “Hurry boys, she’s waiting there for you”.  He then joined Cuomo for the swelling chorus, and if that was not enough, at the end of the song the duo faced off with each other and shredded on their instruments. That's right - Weird Al shredded on the accordion, proving yet again that he is the undisputed champion of the squeeze-box. Check out fan-shot footage of the delightful performance below.

Weezer are close to wrapping up a summer tour where they’ve been supported by the Pixies. The final date of the trek will be in Phoenix this weekend. Weezer then have a couple of dates without Pixies next week.
