When it’s time to place a call to Texas singer/songwriter/guitarist Dub Miller at the appointed interview time, a recording says that the number is unavailable. He quickly calls back about 30 seconds later, but wonders aloud if others calling him get the same message. “It could be Willie Nelson calling to record a duet and you’d miss it!” I offer. But it turns out, that’s not too crazy a thought. Miller recalls how he was booked for a show years ago by Pat Butler, whose husband—songwriter/producer Larry Butler—was a running buddy of Nelson’s back in day. He also produced massive hits for Kenny Rogers and co-wrote with Chips Moman the B.J. Thomas hit “(Hey Won’t You Play) Another Somebody Done Somebody Wrong Song.”
