WEEKEND TV : Pasadena’s Other Parade Airs Sunday

Holiday parades and what we can do about AIDS will highlight the busiest shopping weekend of the year.

“The 16th Occasional Doo-Dah Parade,� Pasadena’s spoof of its slightly more famous New Year’s Day parade, will air live on Channel 13 Sunday at 11:30 a.m. with a repeat at 8 p.m. Hosted by Jay Thomas, Vicki Lawrence-Schultz and Richard Simmons, this year’s edition will feature Pee-wee Hermans, Supreme Court look-alikes and a new routine from the synchronized briefcase drill team.

Sunday will also feature the more traditional “Hollywood Christmas Parade,� 6 p.m. on Channel 5. Charlton Heston is the grand marshal. Bob Eubanks and Leeza Gibbons will host the telecast.

“Unfinished Stories,� airing Sunday from 2 p.m. to 3 a.m., is Bravo’s third annual fund-raiser for local AIDS organizations that will continue every Sunday through December. The all-day event will feature “Talkin’ About AIDS� at 4:15 p.m., in which teens discuss AIDS issues and a repeat of “Red, Hot + Blue� at 7 p.m., which features singers such as Sinead O’Connor and Jimmy Sommerville performing Cole Porter standards.

To commemorate the World Health Organization’s World AIDS Day Sunday and to illustrate the terrible toll AIDS has taken on the artistic community, 32 different cable networks, including Bravo, will be silent for 60 seconds at 8 p.m. in what is called “A Moment Without Television.� VH-1, meanwhile, Saturday at 2 p.m. will pay tribute to Freddie Mercury, the lead singer of the rock group Queen who died of AIDS this week, with a half-hour special hosted by Queen guitarist Brian May.
