What July 4th is for Americans; what Bastille Day on July 14th is for the French; what St. Patrick’s Day on March 17th is for the Irish, and what the Black-Necked Crane Festival on November 11th is for the Bhutanese, so January 4th is for fans of rock ‘n’ roll: a day when so much stuff happened as to enshrine it as a major, rock ‘n’ roll holiday! What, pray tell, happened on this day? Thank you for asking…
