Tangy and funny as much of Mr. Logan's writing is, the play would hardly transmit the contact high it does without the presence of Ms. Midler. As a performer she shares certain qualities associated with her subject: an ability to make the crassest vulgarities sound like crystalline repartee, an earthy glamour and a preening, kittenish imperiousness that's somehow warmly endearing. It is hard to imagine any other actor imbuing the character with the same seductive effervescence - or giving a feeling of perpetual motion to a 90-minute monologue without even standing up. (Dressed in a shapely blue tent adorned with silvery spangles designed by Ann Roth, Ms. Midler looks smashing enough to single-handedly revive the muumuu.)
