Pink got me started on fantastic lady singers of the past when he posted about Shirley Bassey. That lead to the usual path, starting from Bassey, going over Dinah Washington, Aretha, Dusty Springfield, and onwards. Those paths are dangerous because once you begin them, you emerge into the light hours later with your hair on end and crocodile teeth marks on your shins.

Shirley Bassey, “Get this party started”, ie Bassey channeling P!nk (which suits this post!) 😉
Dinah Washington, “What a difference a day makes”
Sarah Vaughan, “Send in the clowns”
Billie Holiday, “Summertime”
Dusty Springfield, “Son of a preacher man”
