Well, certainly one of my favorites, the late great Donna Summer.

This is Summer in her later years.
There are some younger people we've unofficially adopted. One is a young lady who once had aspirations of a singing career. We showed her this video and she said "that is tight." I haven't heard anybody say "tight" in 50 years and then mostly from west coast guys I knew in the army but in this case it fits.
After she died Rush Limbaugh on his show said he'd met her when she sat next to him on a flight. Limbaugh said she was a lovely and gracious lady. She also had a great voice and could really sell a song.
