LOS ANGELES (AP) — Attention pop stars: If "Weird Al" Yankovic shows up at your concert or has tracked down your personal email address, you're likely his next parody conquest.

Such was the case for artists like Pharrell and Iggy Azalea, who are covered by Yankovic in his latest album, "Mandatory Fun."

For his 14th studio effort, released last week, Yankovic had his heart set on Williams' No. 1 smash "Happy." When he didn't hear back from Pharrell's camp, he decided to go straight to the source.

"I somehow got Pharrell's home email address — I won't say how — and I emailed him and asked if I could do the parody," recalled the 54-year-old comedian. "He couldn't have been nicer and he said he was honored to have me do the parody."

Sometimes a face-to-face plea was necessary. Yankovic flew to Denver and waited backstage at Azalea's concert to get permission to use her summer hit "Fancy."

"I talked to her as she was literally walking offstage. I introduced myself, 'Hi. I'm "Weird Al" Yankovic and I would love to do a parody of "Fancy,'" he said. "The next morning I was in the studio recording."

Yankovic's efforts paid off: Billboard reported that "Mandatory Fun" will debut at No. 1 — his first — this week with more than 80,000 units sold. That's almost double the amount his last album, "Alpocalypse," sold in its debut week in 2011.

In a recent interview, Yankovic discussed the surprise success of his new album — which also features covers of Robin Thicke's "Blurred Lines" and Lorde's "Royals" — and the accompanying music video-turned-viral hits.
