Oak Grove is a small town in the northeast part of Louisiana, a little ways across the Mississippi River from Rolling Fork and the Mississippi Delta, the fertile ground of the blues.  And the Magnolia Sisters are an all-woman Cajun band, whose members have changed over the years, but they’re still making music.  Here’s a performance at the Oak Grove Folk Festival of a song they call the Doc Guidry waltz.  The sisters are, from left to right, an unknown fiddler, Ann Savoy, Jane Vidrine, and Lisa Trahan.  I don’t know this song by title, though Oran “Doc” Guidry was a Cajun fiddler who died in 1992.  He only recorded one LP that I know of King of the Cajun fiddlers, for La Louisianne (#115).  There’s a song Doc Guidry medley (‘Tit Maurice & Doc’s fiddle) recorded by  the Savoy-Doucet Cajun Band (Sam’s big rooster. Arhoolie. CD 481. 2000), but I haven’t checked to see if this is the same thing.
