Elton John, Annie Lennox, Nelly, Bjork, Paul McCartney and such Australian stars as Midnight Oil, Silverchair, Kasey Chambers and the Finn Brothers are the latest acts to sign on for events to raise f

Nearly four weeks after a deadly earthquake and tsunami in the Indian Ocean left more than 150,000 dead in Eastern Africa and Southern Asia, entertainment personalities continue to commit to raising and donating funds to relief efforts. Here are some of the latest developments:

• Elton John, Annie Lennox and Nelly have joined the performance lineup for NBC Universal's "Tsunami Aid: A Concert of Hope." Set for Saturday (Jan. 15), the now two-hour telethon has also added appearances by Meg Ryan, Clint Eastwood, Renee Zellweger, Ray Romano, Ben Affleck, Morgan Freeman and Robert Downey Jr.

As previously reported, the event will be hosted by actor George Clooney, and will include performances by Sheryl Crow, Tim McGraw, Christina Aguilera and Kenny Chesney. Viewers -- watching on all NBC Universal-owned channels (NBC, Bravo, USA, MSNBC, Sci Fi, CNBC, Trio, Telemundo and Pax) -- will be encouraged to donate to the American Red Cross International Response Fund.

• Australian rock acts Midnight Oil and Silverchair are regrouping for the country's second major fund-raising concert to benefit victims. Wave Aid will be held Jan. 29 at the Sydney Cricket Ground and will find Midnight Oil playing its first show since late 2002. Silverchair has not played live in Australia in two years.

Other acts confirmed for the event include Nick Cave, Powderfinger, John Butler Trio, Kasey Chambers, the Waifs, Tim and Neil Finn, Missy Higgins, Pete Murray and the Wrights; the latter is a "supergroup" featuring members of Jet, the Living End, Grinspoon, Powderfinger, Spiderbait, You Am I and Dallas Crane.

Organized by six major talent managers, Wave Aid is expected to raise A$1.74 million ($1.3 million) for the Australian Red Cross, Oxfam Community Aid Abroad, UNICEF and CARE Australia charities.

The first major benefit, held Jan. 8 at the Sydney Opera House, raised A$20 million ($15 million).

• Former Beatle Paul McCartney and his wife, Heather, have made a £1 million ($1,891,000) to International Rescue Committee U.K.

"The McCartneys have our deep gratitude for their extremely generous contribution," IRC president George Rupp says in a statement. "It will have a major impact on the capacity of IRC emergency teams in Aceh, Indonesia to deliver lifesaving assistance to tens of thousands of people from devastated communities."

• Icelandic artist Bjork is assembling a two-disc release of remixes of the song "Army of Me," which appeared on her 1995 Elektra album "Post," proceeds of which will be channeled to UNICEF. A number of unsolicited versions of the track have been sent to Bjork since the album's release, ranging "from hi-energy to death-metal," but more are sought to complete the new package.

With a deadline of Monday (Jan. 17), Bjork is calling for new remixes of "Army of Me" to be considered for inclusion on the album, due in late February/early March. All submissions encoded to 128kbs MP3 should be sent to bjorkremixes@gmail.com, including the name of the artist/DJ, remix, full credits and contact information.
