In "Tarzan" Miles O'Keefe, who plays the vine-swinging title character, doesn't say a word (although he flexes his pectorals with great eloquence). He has also been distinctly silent in the media hoopla surrounding the opening of the flick. There is good reason for that. His contract stipulates that he not talk to the press about making of the picture or producers John and Bo Derek until mid-September . . .

As spokesman for Paul Masson, Orson Welles tells us the vintner will "sell no wine before its time." Now someone is saying that the winemaker, its large spokesman and ad agency Doyle, Dane, Bernbach make no payments before their time. They are being sued by talent agency Sidney R. Craig Inc. for alleged nonpayment of commissions on the Welles commercials . . . and while on the subject of managers suing their clients, Albert Grossman, manager of born-again Bob Dylan, is suing the poet pop star for $600,000 in alleged unpaid commissions . . .

Update: A few weeks ago Notes carried an item about an early recording of the pre-Beatles, Lennon-McCartney group, the Quarrymen, of which there is only one copy. That copy is in the hands of the defunct group's pianist, John Lowe. Paul McCartney offered Lowe $10,000 for the record and Lowe refused, feeling it was worth more. It seems that McCartney's offer was one Lowe should not have refused. Last week McCartney's lawyers got a London court to rule that Lowe must surrender the record and any copies of it . . .

Before James MacArthur became well known as Dan-o on "Hawaii Five O," he was well known as the son of Helen Hayes and the late playwright Charles MacArthur. In October, he will star as Hildy Johnson in his father's best-known play, "The Front Page," at the Stanford Theater in Palo Alto, Calif. It is his first appearance in the newspaper comedy his father co-authored with Ben Hecht . . .

Some new works of Rodin may have been discovered. Eleven sketches and a bust that seem to be the work of the sculptor were discovered July 21 at the home of the late Jean Simpson in Craftsbury, Vt. Simpson, who died last year, was an art collector and a philanthropist. The works, which include a sketch of Simpson at the age of 6, signed by Rodin and dated 1903, will be sent to a Boston Museum for authentication . . .
