‘Weird Al’ Yankovic’s 'Mandatory World Tour’ stops at the Tivoli.

No one is off- limits for “Weird Al” Yankovic’s never-ending barrage of parodies. Not Pharrell; not Eminem; not even Michael Jackson. Any popular artist is up for parody, unless they explicitly object to it.

“My personal opinion of a song has very little to do with whether or not I’ll decide to parody it. That decision is based solely on the popularity of the song and whether or not I can manage to come up with a funny enough idea for it,” Yankovic told Spin magazine’s Dan Weiss in a 2014 interview.

“Having said that, I do tend to pick songs that I actually like, because I realize I may end up playing them onstage for years — possibly the rest of my life.”

All it took for “Weird Al” to begin experimenting with comedic music was an accordion and a cassette player. He mailed these demos to disc jockey Dr. Demento, who played them on his nationally syndicated radio show.

In 1 9 82, Yankovic released an eponymous debut a l bum, which included “I Love Rocky Road,” a play on Joan Jett’s “I Love Rock ‘n’ Roll” and “My Bologna,” a parody of The Knack’s “My Sharona.” Over his nearly four decade career, Yankovic has released 14 albums, two EPs and numerous singles, both parodies and original tunes.

“Parody is, almost by nature, disposable,” Yankovic said in an interview with Vice magazine’s Mike Pearl in July 2014. “And yet, people like it so much. Especially if you hear it at a certain point in your life, and then hear it like a decade later, there’s nostalgia attached to it.”

When writing parodies, Yankovic and his band twist titles and lyrics with a hefty dose of zaniness. The fun doesn’t stop with the lyrics. Yankovic and crew have gone to great lengths for videos, meticulously reshooting scene-by-scene videos for “Eat It” and “Fat,” parodies of Jackson’s “Beat It” and “Bad.”

On 12 albums, Yankovic mashed up handfuls of popular songs and transformed them i nto fast- paced polka melodies, including the “Angry White Boy Polka,” which features anger-fueled songs i ncluding Disturbed’s “Down With the Sickness” and Papa Roach’s “Last Resort.”

“I do so many different things, but I only do one thing at a time. I have to keep reminding myself of that. Any time I look at the tour schedule it looks crazy,” Yankovic said in an interview with the Chicago Tribune’s Vickie Jurkowski earlier this year. “As long as I can focus on what’s in front of me and enjoy that, do a good job with that, it all seems to work out.”

Yankovic’s “White and Nerdy,” a parody of Chamillionaire’s “Ridin’,” was Yankovic’s highest-charting single, hitting No. 9 on the Billboard Hot 100 in 2006. His second-highest song was 1984’s “Eat It,” which hit the No. 12 spot.

Yankovic broke into the No. 1 position of the Billboard 200 for the first time with “Mandatory Fun” in August 2014. It was also the first comedy album to hit No. 1 since 1963, dethroning Allan Sherman’s “My Son, the Nut.”

“To this day, I still can’t get over the fact that I have a stinking No. 1 album,” Yankovic said in an interview with Parade’s Michele Wojciechowski. “It obviously feels wonderful, and certainly when I first started doing this, I would never have dreamed that I’d have a career like this 35 years in the future. The fact that I’m ostensibly, I guess, peaking at this point in my life is beyond crazy.”

Throughout his career, Yankovic won t hree Grammys for best album and one for best concept video for “Fat.” His latest release is currently his last with recording label RCA Record, but it won’t be the end of his empire.

“Well, I have to be careful about that, because a lot of people listen to that and say “Oh, Al’s retiring!” he said in an interview with NPR in 2014. “I am not retiring, I intend to keep making music like I have in the past. All I’m saying is, there’s a pretty good chance this is the last conventional album.”
