Saturday Night Function

Saturday Night Function, the name of an early Duke Ellington tune, is a locally created and produced KWMR music program featuring a rich and nourishing gumbo of the blues, rhythm and blues, soul, jazz, zydeco, reggae, funk and contemporary dance music.
KWMR volunteer programmer soul brothers Marc Matheson and Mark Potts created the show, and Jeffry Wilkinson now co-hosts with Marc a classic juke joint atmosphere for late Saturday nights from 10 pm to midnight every week.

Juke (or jook) joints were informal establishments operated by African Americans in the rural South that offered a safe and hospitable place for music, dancing, food and drink, and gambling. Mos' definitely not sanctified by the church establishment, juke joints served as community centers and night clubs for hard working country folk. Well known jazz bands as well as up and coming stars of jazz and blues performed at juke joints throughout the Southern United States.

The term "juke" is believed to derive from the Gullah word joog, meaning rowdy or disorderly. A juke joint is also known a "barrelhouse."

Although gambling, collard greens and alcohol aren't served at Saturday Night Function, discerning listeners may find themselves kicking off their shoes and grooving to our considered and elegantly sophisticated assortment of mellow, lively, funky and hoppin' tunes.

So stick around after Rick's Jazz Café or Greg's Groove for the Saturday Night Function after party. You won't regret it, and you may well want to return - you're always welcome!

Saturday Night Function airs live every Saturday night at 10:00, for two hours. Archived recordings of the show are available for sharing within a few hours. (Scroll down for the archives, which are posted for a week to ten days only.)
