Question: Do you know how old Willie Nelson is? Answer: Who cares? At this juncture in his prolific career, the pigtailed road warrior has nestled securely into the role of American icon. Widely lauded not only for his songwriting and epic marathon performances, but also for his pro-marijuana activism, an evening with Willie Nelson and Family is not to be missed. Adding a dash of Southern magic to the affair is Alison Krauss and Union Station. Question: Do you know how old Alison Krauss is? Answer: Irrelevant. She was made a member of the Grand Ole Opry at age 21. Get to the Greek, order a bourbon, pretend Berkeley has lightning bugs and let Willie and Alison whisk you away to the country.
