Daryl Sherman (Oak Room, Algonquin Hotel, 59 W. 44, Monday nights through April 27). A smart, light-footed songstress whose piping, Mildred Bailey-flavored voice never fails to swing or to please, Sherman is currently appearing on Mondays at the Oak Room, accompanied by James Chirillo on guitar and Boots Maleson on bass. They don’t come any hipper (TT).
