Macy Gray, Paul McCartney, The Who and others are scheduled to stage Oct. 20's "The Concert For New York" at Madison Square Garden to benefit victims and rescue workers from the attacks on the World Trade Center. The event, to be televised on VH1, is also scheduled to include musicians Bon Jovi, James Taylor, John Mellencamp, Goo Goo Dolls, Melissa Etheridge, India.Arie as well as such Hollywood stars Jim Carrey, Jerry Seinfeld, Gwyneth Paltrow and John Cusack. The money raised will go to relief organizations that include the Robin Hood Relief Fund, which helps New York's needy families, and the Twin Towers Fund, established by Mayor Rudolph Giuliani to benefit rescue workers. Meanwhile, Oscar winner Kevin Spacey is gearing up for next Tuesday's "Come Together: A Night of John Lennon's Words & Music" tribute at New York's Radio City Music Hall. Spacey, who will host the event (which takes place exactly three weeks after Sept. 11), said it will "benefit relief organizations and support messages of a nonviolent world (and) will also support Mayor Giuliani's hopes for healing. This is an opportunity for the world to change." The event will be carried live on TNT at 8 p.m. ET, and performers include Dave Matthews, Marc Anthony, Alanis Morissette, Moby, Lou Reed, Stone Temple Pilots, Cyndi Lauper, Sean Lennon and Rufus Wainwright. Presenters include Ben Stiller, Tim Roth, Steve Buscemi, Cuba Gooding Jr., James Gandolfini, Edie Falco and Julia Stiles. And the following Monday, Oct. 8, Liza Minnelli will lend her voice to "HeartSong: The Heroes' Concert," a Broadway and cabaret benefit for the Twin Towers Fund at Manhattan's Bottom Line nightclub. And Thursday night in Miami, some 60 Latin pop stars, including Carlos Vives, Juan Luis Guerra, Gloria Estefan and Luis Enrique, recorded the song "El Ultimo Adios" ("The Last Goodbye"), written by producer Emilio Estefan and Gian Marco. The CD will feature versions of the song in English and Spanish, and proceeds from its sale will go the American Red Cross and United Way.
