Some context: Yankovic was born in Downey, California and raised in Lynwood, California. He is the only child of Mary Elizabeth (Vivalda) and Nick Yankovic. His father was born in Kansas City, Kansas, of Yugoslavian descent, and began living in California after serving during World War II; he believed "the key to success" was "doing for a living whatever makes you happy" and often reminded his son of this philosophy. Nick married Mary in 1949.
Yankovic changed his diet to become a vegan in 1992 after a former girlfriend gave him the book Diet for a New America and he felt "it made ... a very compelling argument for a strict vegetarian diet". When asked how he can "rationalize" performing at events such as the Great American Rib Cook-Off when he is a vegan, he replied, "The same way I can rationalize playing at a college even though I'm not a student anymore." In a 2011 interview with news website OnMilwaukee, Yankovic clarified his stance on his diet, saying, "I am still a vegetarian, and I try to be a vegan, but I occasionally cheat. If there's a cheese pizza on the band bus, I might sneak a piece." Yankovic married Suzanne Krajewski in 2001 after being introduced by their mutual friend Bill Mumy. Their daughter, Nina, was born in 2003. Yankovic identifies as Christian and has stated that a couple from his church appeared on the cover of Poodle Hat. Yankovic's religious background is reflected in his abstinence from alcohol, tobacco, drugs, and profanity. He and his family currently live in Los Angeles in a house previously owned at separate times by Jack S. Margolis and Heavy D. On April 9, 2004, Yankovic's parents were found dead in their Fallbrook, California home, the victims of accidental carbon monoxide poisoning from their fireplace. Several hours after his wife notified him of his parents' death, Yankovic went on with his concert in Appleton, Wisconsin, saying that "since my music had helped many of my fans through tough times, maybe it would work for me as well" and that it would "at least ... give me a break from sobbing all the time." Their deaths occurred following the release of Poodle Hat, which was Yankovic's lowest-selling album in 20 years, but he considered continuing the show and tour therapeutic, saying "if I didn't have anything to distract me, I probably would have spiraled into an even deeper depression. For a couple of hours each night, I could go onstage and put on a big fake smile and pretend like everything was just OK." In a 2014 interview, Yankovic called his parents' death "the worst thing that ever happened to me." He added, "I knew intellectually, that at some point, probably, I'd have to, you know, live through the death of my parents, but I never thought it would be at the same time, and so abruptly."

A: I am still a vegetarian, and I try to be a vegan, but I occasionally cheat. If there's a cheese pizza on the band bus, I might sneak a piece."

Some context: REO Speedwagon (originally styled as R.E.O. Speedwagon) is an American rock band from Champaign, Illinois. Formed in 1967, the band cultivated a following during the 1970s and achieved significant commercial success throughout the 1980s. Hi Infidelity (1980) contained four US Top 40 hits and is the group's best-selling album, with over ten million copies sold. Over the course of its career, the band has sold more than 40 million records and has charted thirteen Top 40 hits, including the number ones "
The stage was now set for the height of the band's popularity. On November 21, 1980, REO Speedwagon released Hi Infidelity, which represented a change in sound, going from hard rock to more pop-oriented material. Hi Infidelity spawned four hit singles written by Richrath and Cronin, including the chart-topping "Keep On Loving You" (Cronin), plus "Take It on the Run" (#5) (Richrath), "In Your Letter" (#20) (Richrath), and "Don't Let Him Go" (#24) (Cronin), and remained on the charts for 65 weeks, 32 of which were spent in the top ten, including 15 weeks atop the Billboard 200. Hi Infidelity sold over 10 million copies and set the bar for rock bands across the country. The band's follow-up album, Good Trouble, was released in 1982. Although it was not as successful as its predecessor, the album performed moderately well commercially, featuring the hit singles "Keep the Fire Burnin'" (U.S. #7), "Sweet Time" (U.S. #26) and the Album Rock chart hit "The Key." The band came storming back two years later with Wheels Are Turnin', an album that included the #1 hit single "Can't Fight This Feeling" plus three more hits: "I Do' Wanna Know" (U.S. #29), "One Lonely Night" (U.S. #19), and "Live Every Moment" (U.S. #34). REO Speedwagon toured the US in 1985, including a sold-out concert in Madison, Wisconsin in May. On July 13, on the way to a show in Milwaukee, the band made a stop in Philadelphia to play at the US leg of Live Aid, which broke a record for number of viewers. They performed "Can't Fight This Feeling" and "Roll With the Changes," which featured members of the Beach Boys, the band members' families, and Paul Shaffer on stage for backing vocals. 1987's Life as We Know It saw a decline in sales, but still managed to provide the band with the top-20 hits "That Ain't Love" (U.S. #16) and "In My Dreams" (U.S. #19). The Hits (1988) is a compilation album from REO Speedwagon. It contains new tracks "Here With Me" and "I Don't Want to Lose You." "Here with Me" cracked the top 20 on the Billboard Hot 100 and the top ten on the Adult Contemporary chart. They were the last songs recorded with Gary Richrath and Alan Gratzer
