Amy Winehouse and Kanye West? Check. Michael Jackson and Paul McCartney? Don't hold your breath.

The final lineup of presenters and performers for this weekend's Grammy Awards is set, and while the show's brain trust managed to corral the two top nominees in the still-grieving West and the wildcard Winehouse for the blowout 50th anniversary show, producers have shot down speculation that the Gloved One and the former Beatle will show despite planned tributes to their legendary work.

The golden anniversary's golden roster will also include A-list presenters like Prince, Ludacris, Bonnie Raitt, Tom Hanks and Miley Cyrus, and musical performances from Kid Rock and multiple nominees Feist, Kanye West, Alicia Keys, John Mayer and Brad Paisley.

But the biggest get is definitely Winehouse, a six-time nominee for her breakthrough Back to Black, including the four top categories of Album of the Year, Record of the Year and Song of the Year (both for "Rehab") and Best New Artist. The troubled British belter's participation seemed in doubt after U.S. officials rejected her request for a visa to travel to the L.A. ceremony, but organizers scrambled and got a crew together in London to beam her performance via satellite.

"I'm raring to go and really excited to be performing at my first Grammy Awards," the chanteuse said in a statement. "I'd like to thank everyone for their support over the last couple of weeks. I'm really sorry I can't be there, but I appreciate that I'm being given a second chance via satellite."

She will take a brief leave from her drug rehab to rehearse Friday and Saturday and presumably be ready to go Sunday.

West, meanwhile, plans to perform two tracks, "Stronger" and "Hey Mama," in honor of his late mother, Donda, who died in November. West is up for eight awards, including Best Album and Rap Album for Graduation.

Grammy producer Ken Erhlich told E! News' Ryan Seacrest on his radio show this morning that organizers are doing their best to avoid a nostalgia-heavy show.

"We made a conscious decision back in November not to do so much looking back but to stay current. Give it a touch of connecting," he said. "You got to connect the dots in music, as you well know, and that's what we're going to do on Sunday."

Here are some of the dots being connected for Sunday's show:

• Tina Turner and Beyoncé in a special duet
• John Fogerty, Jerry Lee Lewis and Little Richard joining together
• Brad Paisley performing with Carrie Underwood
• Andrea Bocelli going octave to octave with Josh Groban
• Fergie harmonizing with John Legend
• Foo Fighters, featuring Led Zeppelin bassist John Paul Jones as special guest conductor
• Aretha Franklin with Mary J. Blige, the Clark Sisters, Israel and New Breed, and Trin-I-Tee 5:7 in a gospel segment
• Herbie Hancock and Lang Lang conducted by famed maestro John Mauceri
• Rihanna with a reunited the Time
• A special Beatles tribute featuring the casts of The Beatles' Love by Cirque du Soleil and Across the Universe, the Julie Taymor movie inspired by the Fab Four's tunes

Ehrlich also confirmed the show would salute the 25th anniversary of Jackson's seminal Thriller but has downplayed the chances of the King of Pop actually taking part.

"Our plans are to honor Thriller, and there are various and so many ways of doing it, and you'll all find out on Sunday," he said.

Other acts slated to perform include jazz pianist Eldar, jazz saxophonist Dave Kos and veteran jazz/pop vocalist Keely Smith. Among those on the presenter roster: Tony Bennett, Akon, Nelly Furtado, Quincy Jones, Stevie Wonder, Jason Bateman, Cuba Gooding Jr., Joe Mantegna, George Lopez, Usher, Chris Brown, Carole King, Natalie Cole, Dave Stewart, Roselyn Sanchez, Juanes, Solange Knowles, Lyle Lovett,  Bette Midler, Cher and Cyndi Lauper.

The "Girls Just Wanna Have Fun" popster will also perform, along with Natasha Bedingfield, DJ Chris Cox, and Fourplay, at a special after-party the Recording Academy is holding for an invitation-only crowd at the Los Angeles Convention Center.

The Grammy weekend kicks off Friday night with Aretha Franklin being feted as the 2008 MusiCares Person of the Year.

That dinner and awards gala, also to be held at the Los Angeles Convention Center, will see a host of acclaimed artists gracing the stage to pay their respect to the Queen of Soul and 17-time Grammy winner, in speeches and song.

Among those performing: Andrea Bocelli, Herbie Hancock, John Legend, Fantasia, Melanie "Scary Spice" Brown, Corinne Bailey Rae, Patti Austin, BeBe and CeCe Winans, and Dan Aykroyd and Jim Belushi as the Blues Brothers. Bill Cosby and actor Blair Underwood will also make a special appearance. Faith Hill was scheduled to sing, but she bailed out after coming down with a bronchial infection. ("I came to L.A. anyway hoping that I'd be able to sing," Hill said. "I simply can't.")

The shindig will also feature a silent auction of celebrity memorabilia, some items of which were inspired by Franklin's career, including a pink Cadillac. The proceeds will benefit MusiCares' program benefiting recording-industry folks who have fallen on hard times.
