On this day in rock history, a riot broke out at an Alice Cooper concert in Toronto  after the main attraction canceled at the last minute. A year later, Cooper blamed an asthma attack, a condition he said he hadn't experienced since he was six.

In 1974, Emerson, Lake and Palmer put out a triple live album called Welcome Back My Friends to the Show That Never Ends ... Ladies and Gentlemen. It featured most of their most famous LP, Brain Salad Surgery, plus a 27-minute version of "Tarkus" that was spread out over two sides. With their tour selling out stadiums across the country, Crosby, Stills, Nash & Young released So Far, a compilation comprised of hits and choice cuts from their two studio albums. Harry Nilsson called upon his drinking buddy John Lennon to produce Pussy Cats. The sessions included a drug-fueled jam session that featured the only known time that Lennon and Paul McCartney recorded together after the Beatles' breakup. Speaking of reunions, Fleetwood Mac's highly successful 1997 MTV Unplugged episode was captured on The Dance.

Celebrating birthdays today are Ginger Baker of Cream, who was born in 1939, Ian Gillan of Deep Purple and (briefly) Black Sabbath (1945) and John Deacon of Queen (1951).
