When Danny Flowers launches into "Tulsa Time," a few folks in the audience invariably think he's doing a cover song. He's not. He wrote it. And he wrote "Back In My Younger Days," "Before Believing," "Gulf Cost Highway" and plenty of other notable songs. Oh, and he's a whale of a guitarist. Flowers plays Saturday, April 3 at the Bluebird Cafe at the "Three Chords & The Truth" show, with James House, Tommy Karlas and Ray Scott. $12 cover. 6:30 p.m. show.
