1966 -At a Beatles press conference in Chicago to promote their American tour, the big topic is John Lennon's quote, "We're more popular than Jesus now; I don't know which will go first, rock 'n' roll or Christianity." Lennon, clearly shaken by the controversy, explains: "I was pointing out that fact in reference to England - that we meant more to kids than Jesus did, or religion, at that time. I wasn't knocking it or putting it down, I was just saying it as a fact."

1968 - Jimmy Page, Robert Plant, John Paul Jones and John Bonham practiced for the first time together beneath a record store at 22 Gerrard Street in London's West End. By their own account, the chemistry was felt instantly as they blast through Train Kept A Rollin'. They also played 'Smokestack Lightning' and a version of Jake Holmes' 'I'm Confused' (soon to become 'Dazed And Confused').

1970 - At Harvard University, Janis Joplin performed what would be her final concert. Her final performance was with the Full Tilt Boogie Band. The Harvard Crimson gave the performance a positive, front-page review, despite the fact that the band used makeshift amplifiers after their regular sound equipment was stolen in Boston. Ended the concert with a version of Gershwin's "Summertime."

1977 - Guitarist Henri Padovani quit the band the Police after nine months, leaving them a trio.

2009 - Guitarist Les Paul died at the age of 94 suffering from severe pneumonia. Paul is credited with developing one of the first solid-body electric guitars, which went on sale in 1952 and contributed to the birth of rock.
