Keely Smith? I had never heard of the woman until I stumbled into a video. Keely was performing during the transition time between the poodle skirt and the mini skirt. Think of the Mad Man years. In between was Keely.
This is Keely singing All Night Long.
For a time she hung out with a cat named Louis Prima who was a force a nature by himself. This was classic fire and ice and sometimes you had to work out which was which. Usually Keely was the ice as Louis was burning up the joint.
This is their rendition of Don't Worry About Me. Mr. Prima passed away in the 1970s. Keely Smith is still performing. For more info on her check out her Wikipedia page.
