Yoko Ono is reportedly set to appear at MTV's O Music Awards.  Billboard.com says the late John Lennon's widow has been tapped to introduce a tribute to Apple Computer founder Steve Jobs, who passed away earlier this month. The segment will feature The Flaming Lips performing a cover of The Beatles' "Revolution."  Billboard says that in her remarks Ono will mention similarities between Lennon and Jobs, and add they both live on through their work and through the way they've affected people's lives.  The Beatles connection is also a nod to the longrunning legal dispute between the band and the computer genius, who spent decades battling over the "Apple" name.  The matter also played a role in why The Beatles' songs were absent for so long from iTunes.

Devo and Cher are among those up for awards.  Devo is vying for the Digital Genius honor, while Cher is a contender for Must Follow Artist On Twitter.  Iron Maiden's followers are getting some recognition as well.  The Troopers are in the running for the Fan Army prize.  Meanwhile, Queen's "Under Pressure" and Metallica's "Enter Sandman" were also nominees, with tracks up for Best Vintage Viral Video.  But the winner in that category has already been announced, with the award going to Nirvana's "Smells Like Teen Spirit."  The O Music Awards honor the digital aspects of music.  The event will take place in Los Angeles tonight at 11:30 p.m. Eastern, with webcasts set for a number of outlets including MTV.com, VH1.com, and OMusicAwards.com.
