No matter how or when you tune in, Sunday's "Kokua for Katrina" event — originating from Kapono's at Aloha Tower Marketplace — should be an entertainment bonanza. You can soak up the music in person or watch via TV in your living room.

The show was to be mostly an on-site party led by Henry Kapono and his singing partner Cecilio Rodriguez. They frequently join forces as Cecilio and Kapono.

C&K will be on hand, of course, but a diverse slate of troupers has evolved.

The concert has been expanded into a statewide TV fundraising event, with participation by seven stations — KFVE, KGMB, KHNL, KHON, KITV, PBS and OC-16 — in a simulcast from 4 to 6 p.m. Sunday. KSSK radio's Michael W. Perry and Larry Price will co-host, with TV network affiliates providing anchor personalities for specific segments.

The performances, at Kapono's dockside nightclub at Honolulu Harbor, essentially are a continuous afternoon-through-nighttime concert from 3 p.m. to midnight.

"C&K will perform, and I'll do a set alone," Kapono said of the fundraiser, which he and wife Lezlee initially planned as a means to raise awareness for Hurricane Katrina victims. A call from Jon Brekke, a Time Warner Oceanic cable official, expanded "Kokua for Katrina" with a commercial-free television component.

Brekke said the unified drive simply shows "Hawai'i cares," particularly because of the Islands' vulnerability to hurricanes.

Hawaiian Telcom is providing the network to accommodate an on-site phone bank for donations and pledges. Kimo Kahoano will lead that brigade.

Entertainment attorney Bill Meyer joined the effort to round up talent, and Dirk Fukushima of Hawai'i Stars Presents signed on as a show co-producer. Michael Harris of the PBS affiliate will direct the TV broadcast, overseeing an eight-camera crew, and Ted Jung of Liquid Planet is providing off-camera support. All TV stations are providing on-air and production resources.

Kapono's anticipates a throng of about 2,000, with thousands more viewing via television. So far, headliners include Grammy Award winner Charles Michael Brotman, a Big-Island-based ki-ho'alu master, and local favorites C&K, Kalapana, Barefoot Native (Willie K. and Eric Gilliom together), Amy Hanaiali'i Gilliom, Inoa'ole, the Opihi Pickers, Yvonne Elliman, slam poet Kealoha, comedian Kaleo Pilanca, Chant, B.E.T., Ooklah the Moc, Kainalu, Harold Kama and others.

From 9 p.m. till midnight, the concert will continue for those 21 and older.

Proceeds from tickets and food and beverage sales will be earmarked for the American Red Cross, Hawai'i chapter, for hurricane relief.

A toll-free number, (877) 44-KOKUA, will accept pledges, and an O'ahu number will be posted by airtime, according to volunteer Lisa Dowd. Viewers may donate at www.kokuaforkatrina.com, a Web site still under construction that will be up and running by showtime and will remain active after the event.
