Be careful when you sign on the dotted line... How much Rolling Stone cost back in the day...

3/15/1955 (64 years ago today) - He signed it and he lived with it, making him honorable to a fault, really: Today's the day Elvis Presley officially entered into a management contract with Colonel Tom Parker, whose show-biz resume included being in charge of "The Great Parker Pony Circus" which featured a troupe of dancing chickens. Somewhat sadly, this is an actual fact...

3/15/1968 (51 years ago today) - The nose-to-the-grindstone ethic pays off: At London's Olympic Studios, The Rolling Stones begin the sessions that would turn out to be "Beggar's Banquet", and they were (more than) serious about making a statement this time around, too, working from 7:00 pm to 8:00 am each day without a break -- The first recordings resulted in "Jumping Jack Flash", "Child Of The Moon", "Jigsaw Puzzle", "Parachute Woman" and a piece-in-progress titled "Did Everybody Pay Their Dues?" which would morph into "Street Fighting Man". The Stones are now officially firing on all cylinders and this is the beginning of an unequaled run of work by anybody else that was considered a "peer". Look it up...

3/15/1969 (50 years ago today) - Janis Joplin graces the cover of the latest issue of Rolling Stone. It costs 35 cents!
