The two will sing a couple of tunes penned by the writing duo of Allen and Sager, which generated several hit songs in the 1970s. The apparently tireless Jackman will put in this appearance after putting in Saturday matinee and evening performances at the Imperial Theatre.
Sager began her stay at the nightclub Nov. 18. Show times are at 8:30 PM with late shows on Fridays and Saturdays at 11 PM.
Among the Allen-Sager songs featured in Oz are "Arthur's Theme (Best That You Can Do)," "Don't Cry Out Loud" and "Everything Old Is New Again."
Feinstein's at the Regency is located in Manhattan at 540 Park Avenue at 61st Street. There is a $60 cover and a $30 minimum; call (212) 339 4095 for reservations.
