4/6/1971 (46 years ago today) - Here's where the infamous tongue logo gets introduced to the world: The Rolling Stones launch their own record label, Rolling Stones Records, and the debut release is considered by many to (maybe just) be the very first world music LP, "Brian Jones Presents The Pipes Of Pan At Joujouka" -- The first "official" Stones album on their own label was "Sticky Fingers", which came out several weeks after the Jones project!

4/6/1974 (43 years ago today) -  "Mommy, Daddy, what were the Seventies like?" "They were exactly like this, kids...": California Jam 1 took place at the Ontario Motor Speedway in Ontario, California -- Co-headliners were Deep Purple and Emerson, Lake & Palmer -- Also appearing: Black Sabbath, Seals And Crofts(!?!?), Black Oak Arkansas, Eagles, Earth, Wind & Fire and Rare Earth -- Attendance: 250,000 -- Ticket price: Ten dollars. Gulp!

4/6/1987 (30 years ago today) - This is probably a lesson in how to not make friends: The lawyers (note plural) for Roger Waters issue a strongly worded statement that said Roger believed himself to be the primary/creative driving force behind Pink Floyd and "therefore he would contest the use of the name by anyone else as well as any former members of Pink Floyd." Was 'Old Billy' on to something...?
