VERY good or great female singer?

I will be performing at the Vet's Club on Wednesday's open mic from 8-11.
I play keys and sing and have electronics that allow me to sound like a full band.
I am always looking for singers that can handle songs like Roberta Flack's The First Time Ever I Saw Your Face and Killing Me Softly and Patsy Cline's Crazy and You Belong To Me and Linda Ronstadt's When You Wish Upon A Star and The Carpenter's Close To You and The Eurythmic's Love Is A Stranger and Toni Braxton's Unbreak My Heart and Carly Simon's Nobody Does It Better and Heart's Alone and What About Love and Crazy On You and Vanessa Williams' Colors Of The Wind and Dionne Warwick's I'll Never Fall In Love Again and Yvonne Elliman's I Don't Know How To Love Him and Etta James' At Last.
I can provide spot on full band accompaniment for these songs and can actually sing them pretty well, but if you think you can do them better than me, then I would love to work with you.
Come to the show on Wednesday and check it out.
I will be going on closer to 8 than 11 and only get 1/2 hour, so come early No opera singers, please.
