The co-main event, also a title fight, will be a battle between Mexican sluggers Julio Cesar Chavez Jr. and first-ranked challenger Marco Antonio Rubio.

The three-division world champion Donaire (27-1-0 18 KOs), who will stake his 26-bout winning streak, will once again be traipsing into new territory as he climbs up to the 122-pound class, a division once ruled by the younger Vazquez (21-1-1 18 KOs).

The pugilist from Puerto Rico entrenched himself in the title in 2010, when he knocked out General Santos City-native Marvin Sonsona. Vazquez Jr, the son of former world champion Wilfredo Vazquez Sr, defended the title twice, but fell prey to the Mexican fighter Jorge Arce in 2011.

Arce has since relinquished the title in order to fight at 118 pounds and Vazquez is poised to reclaim glory. But for Donaire, who was the Philippine Sportswriters Association’s co-Athlete of the Year for 2011, it may be an opportune time to embellish his resume with yet another division title.

Meanwhile, WBO middleweight champion Julio Cesar Chavez Jr. (44-0-1 31 KOs) will be challenged by contender Marco Antonio Rubio (53-5-1 46 KOs) in the co-main event.

Chavez Jr., the son of legendary boxing champion Julio Cesar Chavez Sr., is undefeated, while Rubio is in a two-year winning streak. The fight will follow the Donaire-Vazquez bout and will air at 1:00 p.m. on Studio 23.

Now on its 25th year since it was first recorded in 1985 in the same studio by the likes of Michael Jackson (who co-wrote it with Quincy Jackson), the song “WE ARE THE WORLD” will be utilized again for a noble purpose.

The event, dubbed as “We Are the World – 25 years for Haiti” or “We Are the World 2010” drew in a good mix of singers, rappers and a few actors in what is for most of them a proud moment.

Wyclef Jean, a native Haitian says that he feels like a kid in a candy store, stressing that “What’s bigger than a contribution is that you lend your voice.”  He added that the boy in one of the photos from the Haiti earthquake aftermath could be him if he wasn’t able to get into America.

The new version carries a Southern hip-hop bounce to it and includes rap, furnished by the rappers group led by Black-Eyed Peas’ Will.I.Am.  He is joined by T-Pain, Kanye West, Bizzy Bone, Kid Cudi, LL Cool J, Snoop Dogg, Drake, Mann, Nipsey Hussle, Busta Rhymes and Swizz Beatz.

The solo spots are performed by 15-year old Justin Bieber (who sings the opening lines performed by Lionel Richie in the first version); Celine Dion (doing the difficult Cyndi Lauper part); Josh Groban (assisgned to the  Kenny Rogers and Paul Simon duet); and, Lil Wayne (doing Bob Dylan’s part) among others.

Janet Jackson will be singing the lines of Michael Jackson in a separate recording of this “We Are the World 2010” version.

The other performers who made up the 81-strong choir: Jordin Sparks, Faith Evans, Harry Connick Jr.,  Earth Wind & Fire, Enrique Iglesias, Natalie Cole, Pink, Barbra Streisand, Miley Cyrus, Carlos Santana, Brandy, Melanie Fiona, The Jonas Brothers, Jennifer Hudson, Mya, Tyrese Gibson, Tony Bennett, Julianne Hough, Katherine McPhee, Ann & Nancy Wilson (Heart), Keri Hilson,  Best New Artist Grammy winner Zac Brown, Jason Mraz, Indie.Arie, Mary Mary, Rob Thomas, Usher, Nicole Sherzinger of Pussycat Dolls, the Fray’s Isaac Slade, child prodigy pianist Ethan Bortnick, Maroon 5′s Adam Levine, and actors Jeff Goldblum, Jeff Bridges and Vince Vaughn.

The “We Are the World – 25 Years for Haiti” video which will be filmed in 3D together with the song will premier at the Opening Night Ceremonies of NBC’s Winter Olympics coverage.

Both the new version of “We Are the World” and the accompanying video will be available for purchase through a consortium of on-line and retail partners, with all proceeds going directly to the earthquake-relief efforts in Haiti through the We Are The World Foundation, a newly created non-profit organization made up of board members Quincy Jones, Lionel Richie, Wyclef Jean, Paul Haggis, Randy Phillips and Ambassador Louis Moreno of the Inter-American Development Bank.
