In music history, the most notable events of June 12th have a common theme: transition. For example, it was this day in 1972 that Ronnie Spector, barefoot, left her abusive husband Phil Spector with the help of her mother. It was also this day in 2000 that Sinead O'Connor came out of the closet as a lesbian, and five years later in 2005 Pink Floyd announced that they would reunite for Live 8 for the first time in decades.
