ON AND OFF THE AIR:
* The Fox 45 Clubhouse, WBFF-Channel 45's membership organization for kids that is operated in connection with the station's daily children's programming, has passed the 100,000-member milestone.
And beginning this month, members will be getting a plastic membership card along with the third issue of the publication Fox 45 Tales. In the magazine, Clubhouse hosts Kenny Curtis and Steve Harper offer information about the 10th anniversary celebration currently under way at the National Aquarium.
The two young performers preside over short segments of original material which wraps the cartoon fare on Channel 45 in the morning and afternoon hours. They also make frequent public appearances around town, including a live game show about the environment, "EarthChallenge," which is scheduled at White Marsh Mall on Aug. 16.
Executive producer Phillip Guthrie says schools, community groups or other organizations which would like to involve the Clubhouse duo in events should write a request to him at: Fox 45 Clubhouse, 2000 W. 41st St., Baltimore, 21211.
* Happy birthday, Lucy! The late Lucille Ball would have been 80 today, and the TBS cable service was observing the anniversary with a two-hour run of four favorite episodes of "I Love Lucy," beginning at 10:05 a.m.
Could you have picked better contenders than these? The candy-factory-conveyor-belt episode, the grape-trampling-in-Italy show, the William Holden encounter in Hollywood and Lucy's movie stint as a show girl wearing a huge headdress.
* Further regarding beloved deceased TV stars, Media Monitor believes Michael Landon now holds the record for making the most cover appearances on TV Guide magazine within a short period. This week's edition, in fact, is the first in four not to have Landon's likeness on the front.
Did you notice? Last week's 2000th anniversary issue included a prominent shot of Landon on a previous TV Guide cover from his "Little House on the Prairie" days. The two issues before that, of course, were devoted -- rather mawkishly -- to portraits of the actor. In addition, the June 8 issue, following Landon's public disclosure of his cancer, also featured a full-cover portrait.
* Better late than never, we note an error in a Saturday column last month spotted by reader Mike Henry of Cumberland. Actor James Caan, featured in the first episode of the Arts & Entertainment series "Naked Hollywood" (Sundays at 8 p.m.), did not win but was merely nominated for an Academy Award in 1972 for his role in "The Godfather." Actually, Joel Grey won the Oscar for best supporting actor, for "Cabaret." (However, Marlon Brando also won the best actor Oscar for "The Godfather.")
