Tony Award winner Betty Buckley begins a two-and-a-half week engagement at Feinstein's at the Regency Oct. 22.

Buckley has titled her newest show, Deep in the Heart, and cabaretgoers can expect to hear the singer-actress bring to life such tunes as "Once in a Very Blue Room," "No Pride at All" and "Too Many Memories"; the latter is a composition by Stephen Bruton, a composer-guitarist who will be Buckley's special guest on Oct. 22, 23 and 24.

About her new program, Buckley recently told Playbill On-Line, "I travel a lot doing concert work, and everywhere I go is pretty much like everywhere else now. Every town in America — the resonance of all these towns is the same. I think there's a certain kind of resonance of truth about things that we all go through in our lives. Each song [in the show] is about a certain rite of passage . . . It's real Americana music as opposed to country western. Some of the songs come from the [country-western] realm, but the way that we do them has more of a very open, spacious Americana feeling."

During her Feinstein's gig (through Nov. 9), Buckley will be backed by a quintet featuring Clifford Carter on piano, Paul Nowinski on bass, Jamey Haddad on percussion (Bob Weiner on Wednesday nights), Billy Drewes on reeds (Richard Perry will play reeds on two nights) and Todd Reynolds on violin.

Buckley's performance schedule at Feinstein's at the Regency (540 Park Avenue at 61st Street) is Tuesday through Saturday evenings at 8:30 PM with late shows on Friday and Saturday nights at 11 PM. There is a $30 food/drink minimum at all shows with a cover charge of $45 (Tuesday through Thursday 8:30 PM shows and Friday 11 PM shows) and $60 (Friday 8:30 PM shows and Saturday 8:30 and 11 PM shows). Call (212) 339-4095 for reservations or log on to Ticketmaster.com. In related news: Buckley's newest recording, "The Doorway," will be available at Feinstein's beginning Oct. 22; the Fynsworth Alley release hits stores Oct. 29.
