Pete Townshend (Photo: Rob Kim/FilmMagic)Pete Townshend may often come across as dark and skeptical in his songwriting--but it turns out the 66-year-old Who guitarist has a decidedly bright outlook these days. As he revealed during an intimate and revealing chat Tuesday, he was even able to find a positive way to work through the death of a bandmate.

"I have to say as a guitar player, I prefer working without John," he admitted regarding the loss of the Who's masterful bass player, John Entwistle, who died in 2002. "When John died, there was a hole in the sound onstage and I was able to grow into that and find space."

Regardless, Townshend--who was visiting a New York City Barnes & Noble to promote his new autobiography, Who I Am: A Memoir--concluded that the Who's sound will never be the same without Entwistle. "As a member of the Who creating the incredible, powerful, driving, visceral sound, he's gone. I can't really do that again." (Original drummer Keith Moon died in 1978; his and Entwistle's roles are now handled by Ringo Starr's son Zak Starkey and Pino Palladino, respectively.)

It certainly wasn't an easy road for them; Heart's famously fierce 1977 signature song, "Barracuda," was in fact all about their dealings with the music business's shady, sexist boys' club of that era. But now, as the iconic Wilson sisters release their 14th studio album, Fanatic--as well as their boxed set, Strange Euphoria, and their autobiography, Kicking And Dreaming: A Story Of Heart, Soul, And Rock And Roll--they admit in an exclusive Yahoo! Music interview that the industry sadly hasn't changed much for women, four long decades later.

Miley Cyrus' recent extreme run-in with hair bleach and scissors has fans, fashionistas and most recently, Flavor Flav utterly confused. The two bumped into each other backstage at the iHeartRadio Festival in Las Vegas Friday night. With cameras rolling, Flav greeted her with an enthused "Gwen Stefani!!"

Whoops.

Sharing a laugh, Cyrus brushed off the mistake--and didn't bother to correct Flav, even after sharing a chat, a photo and a hug. She must be used to the comparison to the No Doubt singer and also P!nk, who has an even more identical haircut. It wasn't until they parted ways that someone informed Flav to his surprise that she was not Stefani, but Miley Cyrus! But Flav immediately went back to Cyrus to apologize, and all was well in the world.

Four songs into her set, the Queen Of Hip-Hop Soul stopped her band from playing Chaka Khan's "Sweet Thing," a song she covered on her 1992 debut album What's The 411? "I got a real good friend in the building. He's one of the most amazing artists to ever walk the earth," she said as she introduced Prince.

The 12,000 attendees at the MGM Grand Arena went nuts as the iconic soul artist emerged from backstage, donning '70s-inspired attire—an afro, big-framed, gold metallic glasses, flame-print shirt, turtle neck, and silky, yellow bell bottoms that matched his guitar.
