but the rivalry was also good for business. the mid-city lanes rock n' bowl in new orleans staged annual mock battles billed as "boo vs. beau" during the new orleans jazz & heritage festival, which each year drew more than 1,000 patrons and set attendance records at the venue. one year, mick jagger and charlie watts of the rolling stones paid the $5 admission charge to experience the showdown. one such "battle of the bands" was the centerpiece of a 1994 documentary film "the kingdom of zydeco" by director robert mugge.
