ON STAGE
* Travels With My Aunt (Minetta Lane Theatre): This is the kind of show that provides ammunition for people who hate theater. Originally produced in Glasgow, Giles Havergal's adaptation of Graham Greene's novel is about a repressed English bachelor and his freewheeling, high-spirited aunt. It features four male performers, all dressed identically in conservative suits, enacting dozens of roles -- male, female, and even canine. There's a superb cast, including such expert farceurs as Jim Dale and Brian Murray, but it's a pointless exercise. If the content were stronger (Greene's novel is breezy entertainment), or if there was a purpose behind the all-male cast, this might be more than just an evening of high camp. As it is, ''Travels'' is a trivial evening of show-off theatricality.
* Pal Joey (City Center, May 4-6): Only in its second season, the ''Encores!'' series of neglected American musicals has fully established itself. The first two concert-version productions this year, Irving Berlin's ''Call Me Madam'' and Cole Porter's ''Out of This World,'' provided two of the most delightful musical experiences of the season. The final production, running next weekend, is Rodgers and Hart's ''Pal Joey.'' Although this show does get produced, you won't see it with a cast like this: Peter Gallagher, Patti LuPone, Bebe Neuwirth, and Faith Prince, among others. The book has been adapted for this occasion by Terrence McNally.
* Gentlemen Prefer Blondes (Lyceum Theatre): Speaking of musical revivals, this is how not to do one. This early musical by Jule Styne was presented last year at the Goodspeed Opera House, and is now being showcased on Broadway as the sole offering this season from Tony Randall's National Actors Theatre. On Broadway, it looks wan and listless, and cabaret star K.T. Sullivan, playing Lorelei Lee (the role made famous by Carol Channing in the original production and by Marilyn Monroe in the film), is simply miscast. A lovely score (''Diamonds Are a Girl's Best Friend,'' ''Bye Bye Baby'') provides scant compensation.
