On The Weekend Watch:
RHYMIN' ALL NIGHT -- Whew! For many viewers it can be a whole evening of Paul Simon's lyrical, sensitive music tonight. The durable pop singer is scheduled to perform live in concert from New York's Central Park, beginning at 7 p.m. on the HBO premium cable service (and preceded by a half-hour special preview at 6:30). What is especially cute is that the free performance is billed as a kind of memorial observance of Simon's memorable reunion with partner Art Garfunkel 10 years ago in the Manhattan park. And highlights of that 90-minute concert are also airing tonight and can be seen by all viewers, at 11:05 on Maryland Public Television (channels 22 and 67). It's a regular feature of MPT's begging for bucks pledge drives.
SPECIAL ATHLETES -- It is a thin and uncomfortable line between genuine appreciation and vaguely mawkish pity. But the performance of young athletes who compete with special challenges helps transcend the suspicion that a bunch of celebrities want to promote their careers by appearing on the "International Special Olympics Gala" at 8 tonight on ABC (Channel 13). The show salutes the recently completed eighth International Special Olympics in Minnesota. Among the big names are Arnold Schwarzenegger, Wayne Gretsky, Melanie Griffith, Kirstie Alley, Warren Beatty, Richard Dean Anderson, Don Johnson and Susan Saint James.
