GOOD MORNING: “I always thought (the play) was too long.” Neil Simon wasn’t talking about his newest, “Proposals,” now in its fifth week at the Broadhurst, but about “The Sunshine Boys,” which preems Dec. 8 at the Lyceum. Simon stopped by to see the “Boys,” Jack Klugman and Tony Randall, at the theater Tuesday night. Klugman reports Simon had “given us permission to cut nine-10 minutes” from the original. The 1972 B’way production starred Jack Albertson and Sam Levene and was directed by Alan Arkin; 25 years later, the play is now a co-production between Randall’s National Actors Theater and the Cocoanut Grove Playhouse (where it bowed earlier this year). Klugman says Simon complimented the current troupe directed by John Tillinger. Jack had seen the original production and notes, “It is something to shoot at”: it ran 538 performances. Klugman, 75, and Randall, 77, tell me they would stay in the show “forever,” although it is only skedded to run through Feb. 8. Klugman, who underwent surgery on a vocal muscle in 1989, says his recovery “is a miracle.” He exercises regularly to strengthen the other vocal muscle and “it is stronger than ever.” He performs on stage with a tiny, invisible mike behind his ear. Randall says Klugman “is giving the performance of a lifetime.” This is the third stage venture for the duo, after two “Odd Couple” companies and “Three Men on a Horse.” I spoke to both stars after their matinee performance Wednesday for 1,000 kids from N.Y.’s ghetto. It’s part of the National Actors Theater education program. (The performance cost ‘em $35,000). Between shows, Randall was rushing home to see wife Heather, who is expecting their second child in June (daughter Julia Laurette is eight months old). The extra-exuberant Randall said, “I’m expecting a boy.” CBS airs the Woody Allen-Peter Falk “Sunshine Boys” costarrer Dec. 28. And you can always watch a video of the 1975 film version starring Walter Matthau and George Burns, for which Burns won an Oscar.MANY FORMER KENNEDY CENTER honorees will be on hand at the 20th anni Honors, Dec. 7.
