name 3 singers closest to Holly Cole

I was just listening to her version of "I can see clearly" and "trust in me" ......I would like to explore similar singers in the same vein.

Any suggestions would be greatly appreicated.
Eva Cassidy, Nancy Wilson, Sarah Vaughan, Ellla Fitzgerald, Diana Krall, Dina Washington.
Anita O'Day, Susannah McCorkle, Stacey Kent, oh boy I see where this is going...already we have the nine closest three
Tierney Sutton, Jacqui Naylor, Jane Monheit.
2nds for Eva Cassidy & Jane Monheit.
Also check out Rebecca Pidgeon, who records on Chesky label. Her version of Spanish Harlem is superb. Cheers, Spencer
Rickie Lee Jones, Patricia Barber, and Eva Cassidy.
Eva Cassidy better than Holy Cole, Jacintha,Jennifer Warnes.
Please don`t leave SHIRLEY HORN out,she is one of the Greatest singers that`s alive today.
Eva Cassidy, Jacintha, & Diana Krall...hey, is there an echo in here?

Make sure to get Cole's album of Waits covers titled "Temptation" too!

I'd also include Karrin Allyson. Her "Ballads", "In Blue" and "Wild For You" just grow on you. Allyson Krauss's "Forget About It" is also good, but not jazz.
strange suggestion. well, you know...somehow holly cole reminds me of melissa Manchester
