It sounded like Masters At Work could have done this song, or Blaze. It is very housy/gospel like. The refrain goes something like "its not true old people don't like to dance, and my grandmother is a great dancer... on Sundays".

Great track which I heard on WCLK Atlanta on December 19 of last year. Despite two requests to the station they never solved the mystery...

Cheers to anybody who can help out.
